Tried > if the pll insmod options helps in some way? I checked it out, and I concur. I tried various options for pll=, and tried different modes. NTSC, PAL-M, and PAL-JP all produced a correct picture (PAL-JP a little stretched horizontally), but in vlack and white. PAL produces a colour image, but the lack of the correct number of lines seems to mess it up. The image is correct, but perhaps the field offset is wrong. From a screen grab in PAL mode, it looks like one of the fields is correct, and at the bottom of it, you see 100 extra lines. These look like the VBI data lines from the top of the second field, and some of the image lines! The rest of the second field appears to wrap up the top into the correct place for the second field. I'll put up a png here: http://dolphin.osoal.org.nz/~sfd/pal-60.png I guess I should try modifying the PAL mode setup for number of lines and see if I can get somehting that works. If I do, would you want to put it into xawtv/bttv, Gerd? Stephen Donnelly. --
