thank you for the clarification, most dvd players (if not all) are capable of reading double layer discs, as that is what commercially made discs are for sale/rent.

If I read your post correctly, I would suggest that you go back and study the definition of a dual layer disc.
All a dual layer disc does is extend the capacity of the disc. it doesn't give you the ability to put one movie on one layer and another on the second layer, per se, which is what you seem to be implying that you want to do. "meaning if i burned 1-2 movies and then another on top of it."

That's an expensive alternative to putting one movie on one SL disc @$.20/disc!

no what i meant that if you take a dvd of 4.4 gb and burn about 2 gb on it and then another burn of 2 gb you get the same cap but two layers

?????????
Sorry, but I'm not following what you're thinking of doing.
What do you think that you would be accomplishing by putting them on separate layers?
Having two layers only extends the capacity of the disc. You still only have one logical disc, only 9.4GB (DL) instead of 4.7GB (SL)
Secondly, what you are suggesting is multisession (writing two times to a single disc, which, AFAIK, is not supported for Video DVDs and only partial support for data DVDs. You cannot write two separate sessions to a DVD, single or dual layer.

DVD 5 is a one-side single-layer Disc that fit 4.7GB (4.38GB)of data.
DVD 9 is a one-side dual-layer (doubble layer) Disc that fit 8.5GB (7.95GB) of data.
You can double burned (or +3, +4, etc) or add more data (movies) to the disc, if it is a Rewritable DVD Dics (DVD+RW) "ONLY"
A DVD+R, DVD-R, DVD+R DL, can only be burn "once", not matter the size of the Movie or Movies. Once is start burn it or Finalyzed, that's it. You can't go back to keep burning this kind of disc's 'cos, maybe you have an extra space or wherever.
P.S. Now a Un-Finalyzed disc will play on your PC only, but not anywhere else and you can go back and add more data to it (never done it myself, but I think is how it works).

He's talking about putting 2 movies on a single layer disc. I understand now and it can be done. Hope this is correct link-shrink can do it.

There is a lot of confusion on this point. I think the original question was, "Is there any DVD player that will not be able to read a DVD that had video recorded in multi-session mode where I recorded one movie and then added others onto the disc?"
1) The DVD video format does not allow multi-session video because the menu structure has to include all the video on the disc.
2) The DVD VR format does allow multi-session video. It is used by video set-top recorders and does allow additional recordings as long as the disc capacity can hold all the recordings at the chosen bit rate (quality level). Not all DVD players recognize the DVD-VR format, and I don't know of any computer system that records in that format.
3) Garmoon's suggestion can combine multiple movies, but that recording is done in a single session, not a multi-session; and the method writes one menu that includes all movies.
4) DL discs must have both layers of the same capacity. If a single-session recording for two movies is made according to garmoon's suggested method, and one movie is 4GB and the second is 2GB, the total recording will have 6GB on the disc--3GB on each layer, so the first movie will appear on both layers. A VR recording on a DL disc records to the outer edge and then turns back in. If the total VR recording on a VR disc is 6GB, a little less than 4GB will be on the first layer, a bit more than 2GB will be on the second layer, and the remaining part of the disc will be filled with dummy data to fill the disc so that both layers match in capacity.

I agree with everything that everyone (except TC) has siad. However, the answers are predicated on an "educated guess" of what the TC is trying to do or TC's understanding of what a DL disc is.
I do tech support for a living. I NEVER try to guess what a customer is trying to do, and I NEVER overestimate their knowledge. I was attempting to explain the facts and have the TC articulate in an understandable manner what he/she was trying to accomplish.

JoeRyan:
If I need to answer the original question: the answer is "MAYBE".
but for sure the disc will play on the original electronic equipment that is burning the disc, even if the simple disc (DVD+R, DVD-R, DVD+R DL, DVD-R DL)is not finalyse and recorded on multi-sessions.
Now: Most of the member on this Forum talk about: Burn Movies with a Computer using software that aloud you to rip, transcode, encode, shrink, even "half" edit and burn "AT ONCE". This simple programs are made to do the job very simple to back up your Movies......and is what most of all of you do.
I am not a Video Profesional, But I'am a "DJ" (Dics Jockey for 30 years) and a "VJ" (Video Jockey for 5 years) too. And like you maybe know, I been doing alot of test recording Tapes, CD's and DVD's, not only using a computer but also recording using a profesional Audio and Video equipment too and those kind of CD-Recorders or DVD-Recorders have a remote with all kind of futures and one of them is the "FINALYZE KEY BOTTON".
So "YES" you can record on multy-session a simple DVD "only one time" on the burned section of it, as long:
1.- If you have a space to keep recording on it
2.- If is not Finalyzed yet.
and also "multy times over":
3.- If it is a DVD-Rewritable. (DVD+RW, DVD-RW, DVD+RW DL or DVD-RW DL)

P.S. barnacle' question is confuse 'cos this question have 2 answers.
The first one is:
He think that the DVD's are record it "On Layers" wich IS NOT, is call doubble layer 'cos it could hold doubble data info on it, but on a stray line, not on layers !
The second one is:
The multi-session recording; wich YES can be done !
Live Free or Die.

The 3rd. answer is:
He want to know if it is a DVD Player that "DO NOT" play double layers Disc's or Un-finalyzed; wich the anwer is:
1.-DVD Players been around with "MOST" of the people since 1997, so the very first DVD Players DO NOT play double Layers disc, since they came out on sale around 2004 or the DVD-RW around 2001.
2.-Un-finalized DVD or CD; "ONLY" can be play back on is own recorded electronic equipment (PC or CD-DVD Profesional Player-Burner)
Live Free or Die.

Mrguss--
Multiple video recordings on a disc are in the DVD-VR format, not the DVD-video format. Not all DVD players recognize the DVD-VR format; some very early DVD players lack the firmware. Video recorders and camcorders use the VR format. I pointed this out as the only way to record multi-session video that is playable on DVD players, unlike video data files that are recorded in a data file format.
DVD+RW DL and DVD-RW DL, if they have ever gotten to consumers, will not play on any consumer DVD player. They have a completely different format, and that is their downfall.
DVD+R, DVD-R, DVD-RW all require sequential recording on a single recording layer. DVD+R DL and DVD-R DL are also sequential, but they have two layers, each of which must contain the same amount of data.
DVD+RW is the only consumer optical disc (other than minidisc) to allow random access recording/erasing.

I am not underestimate your knowledge.
I never been use a DVD-VR (support by Sony Play Station 2), DVD+VR or DVD-VR DL.
I been use it a simple CD or DVD to do my milti-session recordings as similar to a tape recording with up to 99 bookmarks titles per disk and I been playing with Un-Finalyze CD's and DVD's too.
I DO NOT KNOW WHAT ELSE TO TELL YOU.

DVD-VR is not a type of disc, it is a recording format that can apply to each type of disc except DVD-RAM: DVD+/-R, DVD+/-RW, and DVD+/-RW. (ram.cfm" class="forum_link" target="_blank">DVD-RAM has its own built-in format for random access memory and can't record the DVD-video format anyway.)
The DVD-video format uses a menu and the table of contents in the process of finalizing a disc. This is easy for a computer because the recording software knows the capacity of the files to be recorded and builds the menu/table of contents around that information. Once that information is written, the disc is closed and finalized. No changes can be made (except on a DVD+RW whose file structure allows the menu/table of contents to reside in address-type files that can be rearranged, unlike DVD-RW that simply is a rewritable version of DVD-R).
When people record TV programs or camcorder "footage" (there's a word that's not going to be useful much longer), the recording device does not know when the recording is going to end. It can't build a menu/table of contents because the amount of content is unspecified. In those cases, it uses a different format, the DVD-VR format, that allows multi-session recording and only builds the final menu/table of contents when the disc is finalized and closed. This is the format that people who record multi-session video recordings use, even though it seems the same as the DVD-video format and they may not be aware that they are using a different recording format. It only matters in the rare cases of very early DVD players that don't recognize the DVD-VR format when they start looking for the original DVD table of contents.
The process of finalizing any disc is merely writing the table of contents that includes the number of data files/tracks, the location of each of them, and their capacity in terms of bytes and length of time. Once that is complete, nothing more can be added because the table of contents can't also be changed (except on DVD+RW discs).
