Seems to be intermittent - I've only  had it lock up once since I
thought I'd fixed it - though may be more livetv related.

After it has started to move again playback of the recording is still stuttering for maybe two seconds until it is smooth again.

Unfortunately this is expected behaviour. The UI thread blocks until
the new player is setup - which will then throw out av sync for the
main player as well.

I tested with live tv this morning before I replied and it seemed to
be working OK.

> The problem with the "Live TV" radio is that the system creates dummy video frames so that it can be treated as regular TV but it then has huge problems with synchronization between the audio and the dummy video. This is the code that I spent more time on that I want to admit before bailing out....

Yep - I hope to get rid of that at some point. The underlying problem
is that the player was originally written with video first and
foremost - audio only (and MHEG only) isn't well catered for.
