Yeah the thought crossed my mind. Getting the mpeg2 to the tv wouldnt be
that hard, but dealing with the osd/ui would be a hassle. It sounds like
alot of work for something I couldnt use. My hdtv doesnt have 1394 input.
If you want to play with sending mpeg data to your tv, there is a util
in libiec61883 called test-mpeg2. It allows you to send/recv mpeg2 data
via firewire.
