Depending on what kernel you are running you may have a problem with the LNA (?) - basically a build in POS amplifier that causes issues.
I had a bad picture on one of the PVR500's tuners, then upgraded my kernel and it went to much worse. I had to patch something and recompile which turned the amp off. I am back to having one decent (although not as nice as the 350) tuner and one crappy crappy one. Yes, its a samsung tuner.
Hauppauge says there is no known issues with the samsung tuners... really.
