Hi, I've upgraded my hardware. Now bktr(4) does not work perfectly as it always did. I've tried two applications xawtv and fxtv. Both show exactly the same reaction. The picture in overlay mode is being drawn, but most of the time only every second scanline. Sometimes the scanlines in between can be drawn and half of the picture stays on the screen for a few seconds making it impossible to enjoy TV. When I keep the window small or pick 320x240 the picture looks quite acceptable. Are there any problems with VIA chipsets? I've tried "options BKTR_SIS_VIA_MODE" but it didn't help. My kernel settings for bktr(4) are now: device bktr options OVERRIDE_CARD=2 options OVERRIDE_MSP=2 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL options BKTR_NEW_MSP34XX_DRIVER options BKTR_GPIO_ACCESS options BKTR_SIS_VIA_MODE Relevant info from dmesg: agp0: <VIA 8377 (Apollo KT400/KT400A/KT600) host to PCI bridge> mem 0xe0000000-0xe3ffffff at device 0.0 on pci0 nvidia0: <GeForce4 Ti 4200> mem 0xddc80000-0xddcfffff,0xd0000000-0xd7ffffff,0xde000000-0xdeffffff irq 16 at device 0.0 on pci1 bktr0: <BrookTree 878> mem 0xdddfe000-0xdddfefff irq 19 at device 11.0 on pci0 bktr0: Hauppauge Model 44804 C108 bktr0: Detected a MSP34255?-?31 at 0x80 bktr0: Hauppauge WinCast/TV, Philips PAL I tuner, msp3400c stereo. uname: 5.4-PRERELEASE FreeBSD 5.4-PRERELEASE #1: Sat Mar 19 01:15:59 CET 2005 i386 The bug was reported in kern/56245 for 5.1 and it still persists. Is there a bugfix available? What else can I try? Martin
