Thanks, I discovered the XvMC-VLD was not compiled in.  Anyway I've
reconfigured
mythtv and recompiled it.  My frontend is now giving me the XvMC-VLD option.
I've now got both
the XvMC option and the XvMC-VLD options selected, but unfortunaly it still
doesn't seem to work.
It now apears to give to me a blank screen and then the system is locked up.

My frontend log now looks like this:

Not sure if I have HDTV - I think it may be.  I'm in the UK and am trying to
play
back Live Digital TV from Freeview.

Thanks for your previews comments.  Have you got any more suggestions?
