DVD2AVI: Problem handling MPG-Files

quite often (S)VHS-Videos have a poor quality ... usually i rip the MPG (DAT) - files and make one single AVI from them using gordian knot. Now i have a case, in which this procedure doesn't work: opening the files in DVD2AVI takes an unusually long time, and i cannot preview the video (fields in the statistics window remain empty...). When i try to set the color space to YUV 4:2:2 the program crashes. When i save the project without making any settings, Gordian Knot reports the following error: File is not a valit dvd2avi project ... Any hint will be highly appreciated!

As i understand you want to open MPEG-1, but DVD2AVI doesn't support it.

@valent: thank you very much for your hint! that hit the spot! I used TMPGEnc to convert the files to MPEG-2, then i could proceed as usual ...
