Interlace is not a problem, it is good. Just verify that the "strobes" are interlace. If so, then that's good. Do not deinterlace or do anything to combat it. Does audio and video go out of sync when you re-encode the video to SVCD format with TMPGenc? This has not happened to me before. What version of TMPGEnc do you have? You can also encode to SVCD format in Ulead VideoStudio. Test that, does it make e difference on the sync? Had you edited the file before encoding it in TMPGEnc? /Swan
