video stops and starts

[Guest]

What does it mean when video stutters when playing?
the video stops and starts through the whole video.
and sometimes the audio is not synced with the video.
this is an mpeg 2 file. playing in win media player 10.
I have win xp home sp2. alienware notebook area 51.
2.9 gz 3 gigs ram 2 hard drives with plenty of space.
nvidia video card.

Did you make the MPEG2 file? Have you known it to play 'properly' in ANY PC?

When you encoded it, was the PC left alone..... encoding video is just about
the most CPU intensive task a PC can be asked to do, and everything that can
be disabled, should be, including antivirus.

This means closing Outlook or Outlook Express that checks for email,
stopping surfing, playing games, internet access etc etc and leaving the PC
to do its own thing. You'll get the same 'stuttering' result if your PC
does not have the specs to encode. You should have at least a P4 (or
equivalent) with 1gb of RAM. The hard drive should be defragged just before
encoding and Disk Cleanup should be run.

Cari, heres what I did, and the results. The mpeg in question played ok in
win media player on my machine, but when I made a compile dvd for tv using
DVD Lab, that has several files included the one movie did the same
stuttering playing from the HD and when I burned it to DVD Blank and played
it from disc. (note this is a dvd compliant disc that plays on a tv
player).This is after I did the defrag and closed anti virus and did disc
cleanup.

Next: I played the same dvd on the tv player and on a friends computer
without the stuttering problem on the movie in question. only happened on my
machine.

Next: I then ripped out the display adapter driver. I inserted the alienware
driver disc and restarted. computer started back up and reloaded the nvidia G
force 6000 adapter. then I did a quick test project in dvd lab studio with
the same problem file and 2 others just for laughs. "That" finished project
authored for tv dvd player played ok. including the problem file.

Now! can it be determined what actually transpired here? note the first dvd
still does not play right even after doing the driver replacement. Only the
one after the driver replacement.

The file that has the problem was created (and or saved) before the driver
replacement so it may be that it will always have that problem unless you
manage to recreate it... ie import from the original source. Still, it
seems that future projects should be relatively free of issues.
