I use my 770 to watch recordings from my MythTV box.

The 770's browser does integrate well with MythWeb. PDA optimized pages for MythWeb would be nice, but the 770 browser is good enough to use it to schedule recordings, etc.

I have a simple script that uses mencoder to optimize and re-encode recordings for the 770. In fact I am working on a simple GUI for it right now. The script optimizes letterboxed NTSC recordings so that they fill the full width of the 770's screen. Quality is slightly jerky, but very watchable.

I realize it may be a little "quaint" but I transfer the files with a card reader, or with scp.
