[mythtv-users] Hang on channel change? Almost working!

[Mark]

I have: Athlon 64, FC5, 19.1, PVR500


I can get live TV, but when I try to change channels, it hangs ( see 
frontend log below ) and the frontend becomes totally non-responsive.  
Not sure where to look on this one. 
Thoughts on what I can try?
Prebuffer read taking too long errors?
Ringbuff?

Here are the ivtv version info as well: ( let me know if I can supply 
more info )

ivtv-kmdl-2.6.16-1.2133_FC5-0.6.2-110.rhfc5.at
