I have a ReplayTV (similar to Tivo), and use mReplay to download TV shows to my mac. I downloaded a show, and want to edit it. It downloads as quicktime file, but I can't edit the file when I open it in Quicktime. The little edit arrows are not there. So I import it into MPEG Streamclip, edit the clip, and then export it. But the audio is not synced with the video. I've played around with it quite a bit and can't figure out what I'm doing wrong. On the export, the settings I am using are: Export to MPEG-4, Compression is Apple MPEG4 Compressor, frame size is 720 x 480 (DV-NTSC). I've tried limiting the Frame Rate and Data Rate but that doesn't solve the problem. Any ideas on why it's doing this, and how I can solve this problem. Please help. Thanks for your consideration.
