At this moment, I have converted many hours of VHS tape footage into MPEG2 using my digital camera and Pinnacle Studio 8. Not having any DVD writer, I have sectioned all movies into 15 min. at DVD compatible quality. These 15 min. sections are just less than 700Mbyte which I burn down to a standard CD. Now I took some of these 15 min. CD’s for playback on a stand alone DVD player (one that can play MPEG files), but that gave a very jerky playback. The list below will highlight this problem.
Just below is a performance rating taken from the Windows Task Manager:
Player: Media: CPU usage:
Windows Media Player Playing a Pinnacle Studio generated MPEG2 (DVD quality) ~70%
WinDVD4 Playing a Pinnacle Studio generated MPEG2 (DVD quality) ~65%
WinDVD4 Playing a DVD directly from disk ~15% <= !
WinDVD4 Playing a ripped DVD (VOB file) ~50%
The question is:
a) What is the real difference between MPEG2 and DVD (65% and 15%)?
b) Will I be able to convert my MPEG2 files to DVD?
c) When I have converted my MPEG2 files to DVD, will the CPU usage fall to 15%?
from the times i have done the same as you , i too have found most standalone drives incapable of replaying cd based dvd files properly.
i believe it is down to the reading of the data which is being done at cd speed and not dvd speed.
i find the same files , burnt to a dvd , play fine in same machines.
try recording to a cdrw and see if that works any better.

Gary probably correct in that, if you put in a CD and the DVD player accepts it is a CD it may only play at say 10x in which case that is not the speed of a DVD which I believe (correct me if incorrect) is equivalent to a 15 speed CD, so if it needs that speed then the CD would jitter as it will not get the data fast enough of the disk.
Having said that I have a made a DVD on a CD (MPEG 2 and menu's) and it played fine on my cheepie machine.
