The thing that concerns me is that it seems like most people that have a PVR500 with the new samsung chips are all having different experiences. Some have claimed that all works great except channel 45. Some have audio problems on a tuner, some have low band issues on one tuner. I myself have been having an issue where the first tuner is staticy on all channels, the worst being the low band channels, but even the good channels are staticy compared to the second tuner which is clear all the way through (except i also seem to have the channel 45 problem as well even thought i don't watch that channel). I guess the differences can be attributed to people in different regions watching different frequencies. But the question is how can the problems be fixed when they can't really be narrowed down? Did Hauppauge do something weird to this card?
