[mythtv-users] HD3000 recording problem in Mythtv- signalStrengthATSC_v4l2(), error: Invalid argument

[Brad Fuller]

I've had some success... I'm not even limping yet, but at least I'm 
crawling...

I've been able to scan the channels on the HD3000 once I set it to "DVB" 
card instead of "HD3000".
I still have to manually /sbin/modprobe cx88-dvb to get the dvb drivers 
to load
I've been able to keep my PVR-250 recording.
I just now have been able to tune to HD3000. I think some of my tuning 
table is off because when I select 2_1 as the starting channel myth 
times out. But, when I set it to 93 (for some reason, there were more 
channels above my cable (top channel 82 on comcast SF-Bay Area) it 
worked. So, I think there is something amiss with the tuning. Don't know 
what yet. I'm don't know how the scanning on mythtv-setup and 
mythfilldatabase from Zap2It works together. Any pointers appreciated. 
I'll have to go back thru the links that geoff, blastzone and Mercury 
have provided (THANKS!)

BTW, when I select the card in mythtv-setup>Input the number that I 
place in:
"Starting Channel" didn't stick for a long time. It doesn't matter if I 
had mythbackend running or not. (BTW, when it's running, there are more 
options (LNB, Stat location... something that is not relevent to my 
situation).


Now, the problems I have are:
* audio echoing on most of the HD channels.
* intermittent sound on a few HD channels
* some video stuttering on HD Channels.
* As I mentioned, some channels tuning incorrect (I assume that's the 
problem)
CPU pegs out on HD channel (I have a AMD64/3000 running FC4-32bit. 
Plenty of power.)

My current modprobe.conf for those interested:
