I've never tested the card under windows; bought them in a 3-pack with 2 friends. 2 are in Linux (Gentoo), 1 in Windows. In Linux, quality on both cards is as described; in Windows, quality is good so it's probably a driver/settings issue. Both Linux and Windows boxes are running on nForce3 chipsets so I don't think it's chipset related. > > I've been able to get it a bit better, but still not near what the 350 > > does by activating DNR; this is set in the local.start-script of my > > Gentoo-box: > > Hmm, I have gentoo too... Doubt that could be it tho'. Nah, just a cool build that allows me to easily upgrade both ivtv and MythTV-CVS using some ebuild-scripts. > > # Fix mediocre PVR-150 quality > > /usr/bin/ivtvctl -d /dev/video1 -c dnr_mode=2 > > /usr/bin/ivtvctl -d /dev/video1 -c dnr_temporal=6 > > /usr/bin/ivtvctl -d /dev/video1 -c dnr_spatial=6 > > > > Hope this improves it a bit for you as well. > > Hmm strange.

I scanned the Hauppauge forums and noticed that under Windows DNR seems to be activated. They were talking about setting it to 8 but that seemed a bit too much for me. I played around and found that these settings seem to give a good balance. >From the forums, it seems there's some more filters and stuff but I don't think they're in the current ivtv-driver (yet). > What is your cable distance?

But even then, if it would be the cable > length / signal enhancements, why would I have it on the composite-in. My cable-provider installed an amplifier in my basement; cable is about 10m where it's split with a 4-way splitter (TV, 350, 150 and 1 free); "high-quality" splitters and cables with filters. Not saying it's professional stuff but it's not your basic cheap plastic splitter and standard coax-cable. The image on TV and the 350 is crisp; only the 150 gives the same streaking/blurring as you are getting. As you said. If you also have it on composite, it's can't be signal strength or tuner related. > Thanks for the re.
