Hi all, I'm new here, so please go easy on me if I post wrong or don't give enough information to describe my problem.
I've used Jarod Wilson's excellent help to setup MythTV on a new computer I'm planning to use as a PVR with multiple PVR-250 boards in it. Right now I have one board installed. Everything has gone beautifully right up to to the point where I pick "Watch TV" in MythTV. When I do that, I hear about 1 second of sound and my system appears to hang (I can't switch to another screen, nor ssh in). I never see a picture at all. I can watch TV (via /dev/video0) in mplayer with no problems, everything works fine there: sound and video both. I can use irw and test my remote. All my devices seem to be working properly. There's some suspicious output in mythbackend.log. When the frontend attempts to watch TV, the following shows up: 2005-02-21 16:17:49.518 Channel(/dev/video0)::Open(): Can't open video device, error "No such file or directory" 2005-02-21 16:17:49.526 Channel(/dev/video0)::Open(): Can't open video device, error "No such file or directory" 2005-02-21 16:17:49.606 ChannelBase: Could not find input: Tuner 0 on card when setting channel 3 I captured the output of the mythfrontend program, and this is what happens: 2005-02-21 16:05:30.140 Changing from None to WatchingLiveTV 2005-02-21 16:05:31.121 Video timing method: USleep with busy wait 2005-02-21 16:05:33.361 Timed out waiting for free video buffers. The 'timed out' message repeats until I reboot. I can't seem to see anything in /var/log/messages or with dmesg. The /dev/video0 file DOES exist, contrary to what mythbackend seems to report, as well as /dev/video, /dev/video24, /dev/video32, and /dev/video4linux. Here's what they look like now: lrwxrwxrwx 1 root root 6 Feb 21 16:18 /dev/video -> video0 crw------- 1 root root 81, 0 Feb 21 16:18 /dev/video0 crw------- 1 root root 81, 24 Feb 21 16:18 /dev/video24 crw------- 1 root root 81, 32 Feb 21 16:18 /dev/video32 crw------- 1 root root 81, 32 Feb 21 16:18 /dev/video4linux I've tried setting the permissions on the videoX files to 666, and the owner to 'fred', but it still responds the same way. In MythTV, the video is configured to use /dev/video0, and send output to "Tuner 0". My kernel is 2.6.10-1.766_FC3, and I'm running Fedora Core 3. Anyone have any ideas, or need more information? I'm kind of at wits' end here. Thanks in advance, Fred
