I got a PVR-500, and I'm having some problems with the picture quality. I think my signal is pretty strong from the cable provider. When I turn off the internal amplifier on the card (in the kernel), I get a snowy picture on some channels and a pretty good on others. When I leave the amp on, I get distortion lines on some channels others are fine. It seems to me the problem could be solved here, but there is a lot of tuning and recompiling the kernel to be done.
Are you sure that some cards are more sensitive than others, and it's not that peoples cable signal is different? If there is a chance I could get a better card, I could return this and get another one. I'm getting the best PQ on most channels by padding the cable with a 3 way slitter and leaving the internal amp on (as it is in the 2.6.18 kernel). I padded my signal by connecting my cable from the wall into the output of a 3 way splitter and connected my computer to another output (nothing on the input). I've ordered actual signal pads (attenuators) and a ground breaker to see if this helps. Does anyone have a tip how to get a better PQ with this card? Is there any tuning that can be done via the driver to improve the signal? Like turning on or off the amp. - Haavar On Nov 28, 2006, at 5:28 AM, John Drescher wrote: > > I currently have a PVR-150 with ivtv-0.8.1 and kernel-2.6.18 and I'm > happy with the quality of the picture.
