[mythtv-users] Same Channel - Two different Type Tuners with different quality

[Steve Nuffer]

I have a PVR350 (Svideo Out to TV) and a PVR 150.  From the same source, I am getting different quality on the same channel.  Channel 28 (Cable-HSRC) is fuzzy on the the 350 compared to the crisp 150.  I have switched inputs and the problems stays with the 350.  I believe this is the only channel that is giving me some problems.  

I wouldn't worry about it but one of my users(spouse), likes to tape several shows on this channel.
