I see the exact same difference in quality with a PVR-500 from last year (Philips tuner) and a recent PVR-500 (Samsung tuner). The Philips was/is beautiful, the Samsung looked like it had MPEG compression "artifacts" all over the place. Since they are in different MythTV boxes, I put the Samsungs into a different recording Recording Profile, and cranked up the quality settings. Now the artifacts are gone, but it still looks a little "grainy".
