I have a rough version of mythroku that succesfully plays my recordings in protocol 31 (mythtv-0.20-fixes) and "may" work for protocol 32 - Ive coded but not tested it.
It can be found at http://members.cox.net/jm_maclaren
There are some rough edges I am working on but as my knowlege of the code is pretty shaky. No livetv yet though if the live tv is initiated then the programs will show up and can be atched while recording.
Enjoy and let me know about any problems
