[mythtv-users] DVB-T Low Signal / High SNR

[Paul Raison]

Hi, just trying to setup Mythtv using a Pinnacle 300i DVB-T card. When 
scanning for channels I'm seeing the signal strength around 10-20% and 
Signal / Noise around 60-70%. It does find channels, but any attempt to 
watch them results in blocky / stuttering video. I get the same with 
command line outside of Mythtv

I know that the signal from the aerial is fine, as I have a standalone 
STB and see signal strength of around 90%.

I've been fighting with this for several days and have been tearing my 
hair out!! Before I give up on the project, does anybody have any ideas 
of what to check, possible probs etc?

Thanks
Paul
