I am using bttv 0.8.46 on a crappy old zoltrix tv card, and it just does not seem to work quite right. When I use xawtv, I get a fairly clean picture, but when I use tvtime, I get a picture that seems to show portions of previous fields. Kinda like it's remembering previous field values and flickering a portion of the displayed frame back and forth. This is not interlace artifacts or any such thing but looking like frame buffer memory problems of some sort. 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 also see errors such as: Nov 21 19:56:25 pc kernel: bttv0: SCERR @ 16dd6000,bits: HSYNC OFLOW FBUS FDSR SCERR* in my message log. The whole output from my bttv module installation: PCI: Found IRQ 11 for device 00:02.7 PCI: Found IRQ 11 for device 00:02.7 bttv0: unloading bttv0: i2c detach [client=Temic NTSC (4032 FY5),ok] bttv: driver version 0.8.46 loaded [v4l/v4l2] bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Host bridge is Silicon Integrated Systems [SiS] 735 Host bttv: Bt8xx card found (0).

I don't have a lot of info on this card but from what I can figure out it's a "Genie TV". The PCB has the number "VP-8790 Rev. 2.1" on it. Any ideas? b. -- Brian J. Murrell
