I think that MPEG2VCR will work with m2v files created from a SA Tivo but not a DTivo, but I could be wrong. Run a search for MPEG2VCR and you should find some posts on the topic.
There are alternative methods for editing tystreams that have been found to work. SpruceUp is not frame accurate but will allow you to insert chapter stops at 1-second intervals. DVD Maestro is frame accurate and will give you the precise control you're looking for.
1. Extract and import your movie into Maestro in the same way that you currently do with SpruceUp.
2. Set your chapter stops at the beginning and end of each segment you want to edit out of the video clip. Make sure you retain a short segment at the very beginning of the clip to retain the header info or you won't be able to author the video later on. A 1-second segment should be all you need for this.
3. Compile the video project in Maestro as a title set.
4. Open up the main VOB file in Smart Ripper. Select the segments you want to keep and re-rip the VOB file. A new VOB file will be generated, less the unwanted segments.
5. Do a simple demux of the new VOB file using TMPGEnc. This will creat an m2v and mpa file. Rename the mpa file with an m2a extension.
6. Reauthor the new m2v and m2a files from scratch using either SpruceUp or Maestro and DVD Patcher as before.
The new files will contain the original video clip but the unwanted segments will be edited out. The beauty is that there is no loss of audio sync using this process. Links for downloading all software can be found in the DirecTV Tivo Hacking forum on page 3 of the How Tos Only sticky thread. I believe Smart Ripper and TMPGEnc can be downloaded from the Doom9.org website.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
