I've read the thread you you mention, and call me skeptical, but I don't buy it 100%.
Yes, a poor cable signal can cause all sorts of problems. But short of doing a comparison between a PVR-500 in Windows and the same card in Linux, you just can't say that you have the tuner definitions 100% correct. I work in the video industry, having worked on a set-top box, and before that, cable modems. The main supplier of tuner chips that we use (starts in "B", ends in "com", you figure the middle out) is the absolute worst. When their datasheet isn't outright lying, it's missing information, and when the datasheet is complete, the reference code is totally different. Then, there's also information that is only given to the largest customers who pay a ton of money. Right now, I have a PVR-250 that is of quality that is much greater than my PVR-500 in the same machine. The TV does show that the signal isn't the greatest - but, when signal runs through the PVR-500, every now and then I get wavy lines and static, which is not visible on the TV, or the PVR-250. Since I have access to the equipment at work, I'll be bringing home a cable analyzer to check my signal level, but not everybody has access to this. I'm hoping that perhaps an upgrade in the ivtv driver (I'm using the 0.2 series) will help out. I might just have to run a Windows/Linux comparison at some point. -- Joe --- "Michael T.
