SVCD stuttering on playback

I've usually been content with burning stuff in Nero and what not and never really had problems until awhile ago. I though it was my burner, but I've recently done a complete system overhaul and upgraded my CD-RW.

Anyway, I can burn SVCDs fine, but when I try to play it back on my computer, it stutters like crazy. I've used isobuster to extract the folders from the bin and it plays back fine from my hard drive. Anyone have an idea of what's going on?

I've used Nero and BurnAtOnce. I burn at 4x for SVCDs. I've actually had problems burning stuff in CloneCD as well, dunno if that's related.

Hi,

Hmmmmm..

Sounds like field order problem.
Demux to audio and video. Use ReStream to make new videofile and choose video Topfield first or progressive and then mux back to mpg. (Try them all 3, nothing checked gives interlaced bottomfield first).

He Means is that Interlaced Video is Displayed in Fields, there are usually 2 Fields per frame and each Frames Fields have to be displayed in a Order, either the Top Field or the Bottom field first and when the Fields are Displayed in the Wrong order then you get a Jumpy effect because Field 2 of a Frame is supposed to be Displayed 1/60th of a Second after Field 1 , But if Displayed in Reverce then each Frame will be displayed in reverce which causes the Jumpy effect...There are Tools Like The one Mentioned (restream?) but the One I use on Mpeg2 files is called "DoPulldown" it is supposed to add Pulldown Flags to NTSC Film Mpeg2 files to make them 29.97fps But it also has features to change the Field order...Interlaced Video Looks Jumpy on PC Monitors anyways because Monitors are not made to Display Interlaced Video because they Display Video in Progressive mode so when Useing Software Video Players such as Media Player you will get Interlace artifacts and some Jumpyness in High Motion scenes but if you use a Player made to display Interlaced Content like WinDVD or PowerDVD it should Look Fine...Well Good Luck

Yah, I use PowerDVD for SVCDs. I used to be able to burn them fine...I'll play around with the progs recommended.

Do I use a separate prog to pull out the *.m2v or *.mpv...or do I just select the mpg file.

Hi,

Yes. There are several tools to separate audio and video.
ReStream works with video only (m2v, mpv).
Look for Tmpgenc or something like that for demuxing.

Some progress...stuttering isn't half as bad, but there are still glitches in regular intervals.
