I have been using fxtv for a few weeks now, initially with the following configuration: Hauppauge Win/TVpci (UK PAL version) Matrox Millenium (4Mb) P6 (Intel PR440FX motherboard, only 1 CPU fitted) FreeBSD-2.2-STABLE XFree86 from the 2.2.1 CDs. brooktree848 driver from -current fxtv-0.42 This worked quite nicely, but there were a few minor problems (see below). I then did the following upgrades: - Upgraded to Xfree86 ver 3.3, hoping that the improved Matrox support would be useful. Made no noticeable difference at all. - Upgraded to fxtv-0.43 (and the matching driver version). All the promised improvements seemed to work, particularly the improved CPU utilisation, but other problems remained the same. - Fitted 8Mb RAM upgrade to the Matrox card, leaving Xfree86 configuration unchanged for the time being (ie. no change to mode lines etc.) Everything else still OK, but the video image appears in the wrong place! The video image seems to be displaced by a constant number of pixels to the left of where it should be; with the initial (small) window, only about the right-hand 20% of the image is actually inside the fxtv window, but with a larger window the strip outside the window remains the same width and correspondingly more of the image inside the window. Vertical position remains correct. Other minor problems include: - The AGC appears poor: I need to make continual adjustments to the brightness/contrast controls to keep a good picture (otherwise bright images look 'overexposed', with bright areas becoming pure white, or else 'dark' images become plain black). - Clicking the 'expand/contract' icon on the toolbar when the window is near the bottom right hand corner of the screen always puts part of the image off-screen (with consequent bleep and error messages). I presume this is logic somewhere not taking account of the different size of the PAL/50Hz picture. - Overlapping windows disable the image completely when in direct video mode. I presume this is simply not implemented - or is it specific to the Matrox? - syslog messages such as "bktr0: ioctl: tsleep error 35 1000f0c" Any ideas for tracking down these problems would be gratefully received!
