[mythtv] Ticket #1219: LiveTV takes a while to start, and video jerks forwards

No major changes I can think of really.  And like I said, I think the 
problem started after using SVN version 8400 but can't say for sure as I 
have to delete the old source code and start again each time as I don't 
have that much disk space :)  Is there a way to find out the revision 
but I'm guessing there's no way.

Certainly not upgraded any compilers or anything like that - checked 
/etc/hostname - has been created 7th of June 2005, although the kernel 
(2.6.14) was compiled on the 28th of Dec 2005 which might possibly be 
the problem - I have to compile it for the DVB drivers, which an option 
might have upset something.  Can't remember why I had to re-compile it. 
  Can't remember when I last did an "apt-get update && apt-get upgrade". 
GCC and G++ both are version 3.4.

I don't really care too much about the long time for Live TV to start, 
but I care a bit more about the jerking issues, and again, I can't 
believe performance would be an issue considering the 1.2GHz backend and 
1.4GHz frontend working perfectly fine for over a year until a month 
ago.  It doesn't really matter too much anyway as I can just adjust the 
timestretch to 0.9 and then back to 1 and it'll be honky dory again, 
until I change DVB tuners or exit/re-enter Live TV.

Cheers - Piers
