Do you remember the last time you saw the driver working with |XImages? I can try and dig up the old driver to test this theory out. I just pulled the latest driver source from pub/FreeBSD/FreeBSD-current/...: -rw-r--r-- 1 root ftp-Free 17180 Apr 5 15:21 brktree_reg.h -rw-r--r-- 1 root ftp-Free 127734 Apr 18 03:18 brooktree848.c -rw-r--r-- 1 root ftp-Free 7345 Feb 26 03:14 ioctl_bt848.h and gave it a whirl. Signals work fine here (i.e. fxtv -disableDirectV) with that version. So that leaves changes to -current since the OS version I'm running (3.0-971208-SNAP), differences related to your newer card, or other hardware differences between our systems. Shot in the dark. Verify that no device on your ISA bus is using the IRQ being assigned to your Hauppauge card. Other PCI devices sharing the IRQ should be OK though. For example, in my system, my SCSI ctlr and Hauppauge share an IRQ: ncr0: <ncr 53c810 fast10 scsi> rev 0x02 int a irq 9 on pci0.10.0 bktr0: <BrookTree 848> rev 0x11 int a irq 9 on pci0.11.0 Randall To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
