Sorry about that, should have used a few more brain cycles on that one. 
Although I have been running my frontend with this code for three or four 
days now with no obvious problems, although I have plenty of spare ram.

I don't think I would go so far as to say a "hell of a lot better" but it 
would be a better solution. I simply haven't had any spare time to look at 
it. I would have to count video frames in GetFrame and re-init audio after ?? 
frames received without audio. This will probably introduce audio lag when 
changing channels and so we would probably end up with the code in 
Reset to get the audio back quicker. Anyway it needs some more thought and 
some experimentation which I haven't got around to at the moment.
