Hauppauge 1800 compression artifacts

post #1 of 2
Thread Starter 
I recently put together a HTPC build to replace a Sony DHG-HDD500. I have OTA and cable, and my location necessitates keeping my backwaters (analog and a few QAM stations) cable company subscription to get many of the Denver area stations.

On the Sony box, the QAM channel quality was excellent. However, I'm seeing really bad compression artifacts on the 1800, particularly halo artifacts on scenes with solid color gradients (i.e. sky, shadows, etc). It's very distracting. TV viewing is currently through WMC.

Does the 2250 do a better job in this regard? This weekend, I plan to do some testing with an AverMedia Duet (currently handling my OTA needs). I think I could probably shoe-horn another one of those in my case, if need be, but I'd really like to keep room available for a discrete video card, should I upgrade in the future.

Thanks for any insight.

I started thinking about other variables that could be a problem (not necessarily the fault of the 1800).

My display is a Panasonic TH-42PH9UK. It's connected to my AVR via HDMI, so I'm not getting1:1 pixel mapping (used the overscan correction tool to size the output). That could be the source of the problem, right?

I also have a DVI blade on the Panny that I could run straight from the PC, but didn't do that originally, as I'd then need to deal with a separate (optical) cable run for audio. Plus, there would also be one more cable for my wife to complain about seeing. Fun, fun!
