The video is jerky, not to an unwatchable point, but enough to annoy me.
I cannot figure out the issue though. Both TV's that I play it on are PAL, but of course are capable of all NTSC formats. Even on my PC (monitor = DELL 2408WFP) it still shows the same problem.
I am also under the assumption that both my TV's are not 3:2 capable... could this be the culprit? Could my monitor not be capable of this also?
If it shows a problem on the PC monitor then perhaps there's a file problem.
Why don't you post a small section so that we can take a look.
Another option would be to open it in Virtualdub and using the right arrow key,
step through it a frame at a time. Describe what you see. Unnatural jumps from
frame to frame or duplicate frames are things to look out for.

Well, opening the video file in VirtualDub gave an initial error of:
Quote:AVI: Stream 1 (audio) has a non-zero start position of 834 samples (+42
ms). VirtualDub does not currently support a non-zero start time and the
stream will be interpreted as starting from zero.
I then went frame by frame to see if, as you said, there are any unnatural jumps or duplicate frames, and from what I can see, no, but then again it could be my lack of knowledge on this subject.
Which program can I use to grab a small section of the .avi and post here for you?
Virtualdub, of course. Open your file and
set "audio" and "video" (at the top) to direct stream
copy.
Depress the left shift key and drag the pointer to an appropriate section
that shows the problem. Keeping the shift key depressed ensures that you stop on a key
frame, which is what you want.
Use the start selection button to start the cut (button at the bottom 2nd from
the right). Then drag the pointer a little bit further (perhaps 3 or 4 minutes?)
and use the end selection button, last on the right .
When the selection is made, go to file/save as avi, and it will spin off that small
section. Post it to one of the file hosting sites.
http://www.mediafire.com/, for example. When it's uploaded copy and paste the
download URL in here and we'll take a look.
You didn't say where the file came from, but somewhere in its history it's been
poorly converted and some frames have been dropped - this causes the jerkiness.

The situation may be irretrievable, but it's possible the Avisynth wizards
at videohelp.com may be able to assist.
A lot of those guys hang out in the "video conversions" forum -

Give it try .
After speaking with someone over at videohelp, it is as you thought, "irretrievable".
