I have Cinelerra working and am trying simple editing like removing extraneous head and tail frames from .vob files that were captured from VHS or Beta tape with xawtv and converted from it's default .avi to .vob using videotrans because Cinelerra will not work with .avi files.. After editing I render the project to a mpeg4 file that views with the audio out of sync.. I tried both ways: a single .vob file with muxed audio or separate video, m2v and audio, mp2 files.. If I render either way without editing, the sync is fine... I suspect this may be "normal" but can't seem to find any clues on the Web... Most of the forums I've checked seem to mostly talk about getting the program running in the first place.. No easy task it seems.. I didn't "sail" through it either. <grin> Any comments appreciated!! BTW I got one suggestion that I didn't have enough memory, 512mB; so I upfitted to over 1gB, with no obvious improvement.. The CPU is a Duron 1.3gHz which should be fast enough according to most accounts.. I don't think it's the HD's because rendering unedited files are in perfect sync...
