I want to use kmttg to re-encode an HD show from my S3 so that it will play on my S2. Which encoding profile will convert an HD show to a format that can play on an S2? If multiple profiles work, which will give the best quality? Also, .mp4 files do not show up on my Tivo for manual transfer from my PC (using Tivo Desktop). Is there a different encoding format that will show up with Tivo Desktop, or do I have to use pyTivo to transfer the re-encoded file back to my Tivo?
