I have an issue with my PVR-500 on mythtv that I have not been able to 
resolve.
 
I am using the latest rpm from atrpms of mythtv and am currently have 
problems with my master backend server when I am changing channels while 
watching live tv.
 
This all appear to have started when I upgraded to the latest kernel 
version of Fedora core 8 version 2.6.25.14-69.fc8 (64 bit version)  and 
I can not go back because some of the modules I need for mythtv to work 
on the older kernel are no longer available via atrpms.
 
******************* Now to get down to the problem  **************
 
When I first enter live tv the video and audio is clear.  When I go to 
change channels the video stays clear and the audio becomes just 
static.  If I exit live tv and come back in the channel that had static 
now has clear audio.
 
I was using the ivtv kernel version from atrpms but then remembered that 
the ivtv driver is suppose to be included in the current linux kernel so 
I removed it. After this Linux was able to see the PVR-500 but it did 
not appear to have initialized properly since Mythtv did not recognize 
the card.  I then noticed that none of the v4l-xxxx firmware libraries 
did not exist in the /lib/firmware directory so I downloaded the latest 
libraries from the ivtv site.  Mythtv now recognizes the PVR-500 but I 
have the same issue with static as soon as I change the channel.  
Another interesting thing is that recordings made by the PVR-500 are as 
clear as they have always been.
 
I am not sure what additional information would be required so please 
let me know.  Any assistance in this matter would be greatly appreciated.
