Careful, some tvtime filters are based on showing data from old fields, when motion isn't detected. You might just be seeing artifacts from poor algorithms, but I kinda doubt it based on those weird errors you're getting. How does the effect change when using greedy vs greedy2frame vs weave vs linear? > I understand that xawtv only show every other field while tvtime shows > both fields, de-interlaced so this seems like an issue with trying to > use both fields at once. I don't think it's an issue with showing both fields at once, but tvtime does keep, if it can get them, three buffers at all time while the card is writing into the fourth one (which is why we like to have you use gbuffers=4). These old buffers are used for our reference frames. > I also see errors such as: > Nov 21 19:56:25 pc kernel: bttv0: SCERR @ 16dd6000,bits: HSYNC OFLOW FBUS FDSR SCERR* This does freak me out. -- Billy Biggs [EMAIL PROTECTED] -- video4linux-list mailing list Unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/video4linux-list
