[mythtv] Tracing Channel Change

[Matthew Carnevale]

Related to channel change times also, I notice on my system that it can 
sometimes take an EXTREMELY long time to change channels, in the order 
of 5-15 seconds or sometimes more.  It depends on how long the same 
channel has been playing for.  This also affects how long it takes to go 
back to the frontend menu, but dosen't seem to affect how long it takes 
to enter a pause.  Any thoughts on this? I'm running my ringbuffer on an 
ext3 formatted drive, could that be the problem?

Just curious if anyone else has had this on their systems.  This problem 
occurred while I was using an analog capture card and hasn't changed 
(I'm now using a DVB-T card). 

Cheers,

Matt
