[QUOTE="mm1352000, post: 1156782, member: 82144"] I also wouldn't expect it to affect the picture quality, but I might expect it to affect the "rapid movement" issue (which is why I mentioned it). Ideally the source frame rate (PAL 25/50) should match the encoder frame rate, which should also match the display refresh rate. You mentioned that your TV doesn't support 50 Hz, so you already have a problem there. Frames will be repeated when displaying 50 Hz content on a 60 Hz TV, and this can be seen as movement judder. This problem would be much less obvious with the 29.97 fps WMC TV/recordings (because 29.97 x 2 = 59.94 fps, which is a much closer match to 60 Hz than 50 fps is). It's entirely possible there is a bug in the settings display (as previously mentioned, not many people use analog TV anymore. Only the log files would be able to confirm... I thought the "sharpness" and "contrast" could be helpful, but I guess you tried them (if they were available). I would guess 2 and 5 (and maybe 4) are from the PVR-150. Did I guess right? :) In my opinion all your screenshots are pretty reasonable for analog TV picture quality on a PC. My picture quality (at least as I remember it now, several years later) was like 1/4/5 at best (except when viewing a VCR via composite/s-video input). My experience has been that lower signal strength/quality or interference/noise cause the "grainyness" like in 1 and 3. No encoder will be able to fix that. If that is what is bothering you then I would suggest to try to remove splitter(s) and/or add an adjustable amplifier/attenuator and see if that improves the situation. As previously mentioned: [LIST] [*]a PC is a very noisy electrical environment; attempting to filter out the noise usually leads to grainy (under-filtered) or "soft" (over-filtered) picture quality [*]analog-to-digital conversion for many "modern" analog inputs is optimised for lower cost highly integrated circuits/chips; lower resolution/quality A-to-D leads to lower picture sharpness/detail [*]the encoders (software and hardware) are optimised for high speed (real time) encoding at SD resolutions [/LIST] [/QUOTE]
