I'm having a problem with fxtv 0.45, the latest bt848 driver (2.2-stable as of about two days ago), and WinCast/TV dbx. Specifically, fxtv dumps core. Here's what I got from gdb: Starting program: /tmp/fx/./fxtv Xlib: extension "XFree86-DGA" missing on display ":0.0". Xlib: extension "XFree86-VidModeExtension" missing on display ":0.0". Warning: Actions not found: TVSetChannel Program received signal SIGBUS, Bus error. 0x17e1b in TVSCREENGetCurVidModeGeometry (s=0x63860, width=0xefbfd662, height=0xefbfd660) at tvscreen.c:180 (gdb) print *s $1 = {display = 0x6b800, screen = 0, visual = 0x74a00, visual_modes = 0x7e0e0, num_visuals = 3, active_visual = 2, fb_visual = 0x74800, base_addr = 0, pitch = 0, bank_size = 0, ram_size = 0, vmode_ext_supported = 0, vmode_majv = 0, vmode_minv = 0, vm_list = 0x0, vm_list_len = 0, vm_startup = 0} Line 180 attempts to dereference vm_list, which is NULL. What I don't know, is why vm_list is NULL. The card appears to work properly under Windows (after I yanked out my SMC network card :). Also, I briefly had a version of fxtv 0.44 which would start up and display static, but could not be coaxed into displaying anything from my VCR. I thought this might be a kernel/user level mismatch (the program was built against older sources), so I grabbed 0.45 to get everything in sync. Any ideas would be greatly appreciated. Alex
