Hello again. I have some updates now that I've been able to make some further tests. 1) My Pinnacle PCTV HD Pro (800e) stick does, in fact, work correctly under Windows. The scanning detects the one channel we're running over our closed circuit cable (channel 3) and displays it on-screen just fine. (audio over channel 3 works as well) 2) Devin, my installation process is "hg clone http://linuxtv.org/hg/v4l-dvb; cd v4l-dvb; make rminstall; make distclean; make; make install" This appears to install everything v4l-related as modules in the appropriate directories. For instance: > uname -r 2.6.24-24-server > find /lib/modules/`uname -r` -type f -name em28xx\* -o -name tvp\* /lib/modules/2.6.24-24-server/kernel/drivers/media/video/tvp5150.ko /lib/modules/2.6.24-24-server/kernel/drivers/media/video/em28xx/em28xx.ko /lib/modules/2.6.24-24-server/kernel/drivers/media/video/em28xx/em28xx-dvb.ko 3) tvtime still hangs when launched. 4) Running zapping gives the error "VBI Initialization failed. /dev/vbi0 (Pinnacle PCTV HD Pro) is not a raw vbi device)". Continuing on and trying to choose the "Preferences" menu option segfaults the program (and this is the Ubuntu-distributed "zapping" package) 5) Running Paul's suggested "mplayer" command gives the following: > mplayer -vo xv tv:// -tv driver=v4l2:alsa:immediatemode=0:adevice=hw.1,0:norm=ntsc:chanlist=us-cable:channel=3 MPlayer 1.0rc2-4.2.4 (C) 2000-2007 MPlayer Team CPU: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz (Family: 6, Model: 23, Stepping: 10) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection. mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support.

So the surprise to me is that the Pinnacle device is not actually broken. By this point, I had been sure it was a hardware problem. Now I realize that it's something else. And so I would again appreciate any suggestions you might have. Thank you once again!
