Hard to tell from those log snippets. That would be one explanation
but it seems that this should be working so long as you allow MHEG
stream recording in your recording profile (the default option).

The first thing to do is get a good log file. Run mythbackend with
"-v record,channel,siparser" and about 2 minutes before a program
ends, enter LiveTV. Now wait until the frontend gives you the error
message and then end the frontend and backend processes. Now attach
the log from the backend to the #3326 ticket so I can have a look
at it.
