When i use DVD Shrink, it takes from 30 up to 90 minutes to decrypt and recompress the content of the original disc, depending if it's a DVD5 or DVD9, as well as the total amount of video materials; i read that prolonged exposure to heat, may deteriorate the life span of a DVD disc and player.
This concerns me as to preserve my original DVD discs, but i wonder if i have to worry about it; it's logical that after decrypting and recompressing with DVD Shrink, both the DVD disc and player will heat up, but this never concerned me, since the same happens when you play a 2+ hour DVD movie on your PC; therefore i thounght that if it's safe to play a movie for over 2 hours, should be no problem to use DVD Shrink for decrypt and recompress for less than that.
My doubt is, regardless of you PC capacities, which is the maximum time reccommended to use DVD Shrink, without putting in risk the life span of my DVD discs and player due to heat exposure? is it safe to use DVD Shrink as long the total time to decrypt and recompress is 90 minutes or less?

The only problems that I have heard of in relation to Shrink and heat has to do with the fact that Shrink is very CPU intensive and you computer can overheat, especially if it is a laptop. But if you are worried about heat in relation to your disk, then rip the file to your HDD first and then use Shrink, this will cause less stress on your drive, since the disk is not in there for 90 minutes.

I appreciate your comment, specially the info about DVD Shrink being CPU intensive (which i ignored) but the question is... is it ok to have the disc playing for 90 minutes or less, in the matter of preserving integrity and life span of my DVD discs, while using DVD Shrink? is there any difference or is safer (in the matter of overheating on both the disc and the player) from reading the disc with DVD Shrink throw 90 minute or less, as to playing the disc/movie for 120 minute or more with Power DVD?
I know it sounds ilogical, since the longer it takes to play/read a disc, larger is the disc's heat exposure, therefore playing a 2 hour movie on your PC, should be more harmfull to the disc, but i have never heard any reccommendations as to avoid playing movies on your PC... that's why i have this doubt.

Here is the answer to your question can heat hurt the disc? Yes and no the DVD sits in your computer if that is what you use it to watch a movie. So it takes just as long as it does to read the info and save it to your hard drive. Are you following me so far? Now what I have done is bought an external hard drive that is just for movie burning. I save the files to that so that if I need to make a copy or if I get a bad burn whatever. You see so you read the movie once and go on from there.

I don't think the amount of heat we are talking about here will affect the disc life at all. Some things need a threshold level to be exceeded before damage occurs and i think the disc would have to get too hot to touch before you start getting any damage. It certainly is not going to get as hot as a disc on a dashboard of a car in summer, and discs can survive a treament like that, as long as it doesnt take the heat too long, like a few days or so. The computers internal fans keeps the temps fairly low for most all components. Yes we are burning stuff, but the lasers don't get that hot, or they would burn thru the disc. The media is photo sensitive, and i think light has more to do with burning discs than heat. Now if the disc comes out of your drive like a hot potato, then we have a heat issue going on. :)

I burned almost all day yesterday and noticed that my 'puter was running overly warm. I put a small fan in front of it to assist with heat dissapation and it really cooled it down. So much of a difference that I am going to use the fan anytime that I burn from now on. Do I need it? Probably not, but it certainly won't hurt the machine. I burned up my last motherboard due to overheating and don't want it to happen again.

Sorry to hear about the MB there 9mmruger1. Most of the time heat becomes an issue, it's the CPU that's overheating, and not the DVD disc. ematrix brings up a good concern, but i don't think there is anything to worry about as far as using shrink on a disc and getting disc heat issues. What about ppl who burn DVDs in middle eastern countries where the day temp is 104f or higher each day. If disc broke down at temps higher than room temp, they would have to refridergate blank media to keep it from going bad. Honey,, could you get me some more Verbatims out of the freezer?

Thank you all, i really appreciate your comments; i assume then that as long that the discs aren't exposed to heat at prolonged periods of time (several hours or even days) there should be nothing to worry about, and having DVD Shrink reading your discs for 90 minutes or less (during the decryption and recompressing process) is perfectly normal and safe for your DVD discs.
Therefore as long as your computer is well ventilated, throw its internal ventilators, or even asisted by an outside fan (which i actually do and indeed lowers the internal temperature) will prevent overheating of your computer, and lower the heat exposure on discs to a minimal.

MaxBurn, I agree totally. The heat was not coming from the burner, but from the CPU which toasted the MB. I was freaked. New computer less than 2 months old. Warranty covered the repairs, so I am just a little self concious about the heat thing. I put my hand on the top of the cabinet and it was hot to the touch, so I decided that the fan was in order. Did the trick, after about 5 minutes the cabinet was cool to the touch.
I'm happy.

You found a simple and easy solution to your cooling problem. Some CPUs just seem to run hot, and that may be something to do with either chip design or manufacture. I rip movies all day and all night, and my cpu fan kicks up speed during encoding, but thats because shrink is using CPU. Once the encoding is done, the fan kicks down to a barely on speed. I don't have a temp gauge, but my PC tower never gets hot to the touch no matter what i am doing, or how long it has been on. Heat distroys CPU efficency, so the cooler you can run, the better for your CPU.
@ematrix
Don't worry about disc heat in your computer. Worry that the disc you put in your computer might have been made by CMC. :)

MaxBurn, sorry if i sound dumb, but what do you mean to worry that the disc you put in your computer might have been made by CMC?

Thanks for the advice, i think i understand what you mean, as to avoid buying cheap blank DVD discs of non realiable brands... i have been using LG and Samsung 8x DVD-R, and currently also using Sony 8x AccuCORE DVD-R, and have a couple of Sony 2x AccuCORE DVD-RW, i think i'm not mistaken to trust only in these brands, but absolutely i would never use brands like Imagion or Princo.
Actually i remember having a bad experience 2 years ago, when i had some old VHS family recordings preserved on DVD, but my mistake was putting them in Princo DVD-R... first time they played fine, but after that the movies began to erase, one after another; since then i don't rely on other DVD-R brands, than the ones i mentioned earlier, since sometimes the stuff you record on DVD is unreplaceable.

ematirx,
Usually i am not so cryptic in my comments about CMC :). The sonys you listed are good, i would have to see what the media codes out on those LG and Samsungs before i could say (you never know who makes this stuff until you do some checking) DVD Identifier a free program here, will tell you who made those discs. The CMCs that i had were under memorex and Verbatim Data LifePlus brands (this was a few years ago). I know better about memorex now, but the Verbs snuck up on me. I only go for Taiyo Yudens and some Verbatims. There are other good manufactures out there, but not many compared the the crap media makers. Usually if the media is made in japan, you are doing ok. The process you described is much like timber rot, only in these cases it is dye rot. Data may be good at first, but like quicksand, your movies get sucked up by the evil empire CMC Magnetics.. Sorry, i started to foam at the mouth. By the time you discover the media problem, it is too late to save it. Watch your movie slowly disolve into the rotten dye... All this can be avoided just by using good media.

I did some digging and the LG DVD-R discs i have been using are CMC MAG AE1... so far i have no problem reading these discs, i have used them mostly to backup data from my PC, but should i worry? am i going to loose all my data stored in these DVD?

WORRY!
I would back those CMC discs up on good media quickly, if the data is important. If not, don't even back it up. You are trusting your data/movies to something known to be bad, and go bad, staying bad, its just bad all over. Data is supposed to be less finiky about media type, but i wouldn't trust a CMC disc for anything data or movie. It's not really backed up when its on a CMC disc. I have probably 75 movies left to back up that are on CMCs. I hate doing them because i am trying to save the things even with errors. On some i just give up, or its too late, the thing is gone. Also getting lots of CRC errors, suddenly windows secretly throws your drive into PIO mode slowing you down to a snales pace.... No CMC has given me tooo many headaches for me to sit back and quietly complain. Im gonna complain LOUDLY! and try to get everyone to avoid these things like the plague.
