I had a bad problem with all of my (s)vcds being jerky during playback. Well it seems to be solved. I got so upset that I deleted both versions of tmpg that I was using(2.53, 2.59). Then I reinstalled it and now everything is working fine. Maybe the program becomes corrupt after using it for a given length of time. I was using mine for 4 months before it started acting up. Any body else try this? And if so what was your result?
