I am running mythtv-0.18.1-112.rhfc3.at on Fedora Core 3 (installed from the at-stable repository via "yum"). I have a pcHDTV-3000 card with the 1.5 version of the driver (the only one I could get to work).
I am literally tearing my hair out over this. I had it working last night; I even did a delayed recording just to verify that all of that stuff worked too. Everything looked good. Now the capture card has suddenly stopped working. All I did was stop and restart mythbackend, and everything is broken. I have tried rebooting. I have tried dropping the mythconverg database and completely rebuilding it. Nothing has helped. The output from dmesg shows that the driver is loaded and the card is recognized: cx2388x v4l2 driver version 0.0.4 loaded pcHDTV HD3000 Driver Version 1.5 ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 10 ACPI: PCI interrupt 0000:02:01.0[A] -> GSI 10 (level, low) -> IRQ 10 cx8800[0]: found at 0000:02:01.0, rev: 5, irq: 10, latency: 32, mmio: 0xdd000000cx8800[0]: subsystem: 7063:3000, board: pcHDTV HD3000 HDTV [card=14,autodetected] cx8800[0]: i2c register ok tuner: Ignoring new-style parameters in presence of obsolete ones tuner: chip found at addr 0xc2 i2c-bus cx8800[0] tuner: type set to 51 (Thomson DDT 7610 ATSC/NTSC)) by cx8800[0] cx8800[0]: i2c attach [client=Thomson DDT 7610 ATSC/NTSC)] cx8800[0]: registered device video0 [v4l2] But if I fire up the myth-frontend and try to watch TV, I get this in the log: 2005-06-05 09:05:04.903 Changing from None to WatchingLiveTV 2005-06-05 09:05:04.920 Error: Desired subchannel not specified in freqid "3", Using 1. 2005-06-05 09:05:05.014 HD5 Error: could not obtain sync 2005-06-05 09:05:19.972 Couldn't read data from the capture card in 15 seconds.

After this, myth-frontend will return to the initial screen, but if I hit ESC and try to exit, it hangs (borderless window, zero response within window) and I have to kill it. Is there anything I can do to debug or diagnose this short of starting all the way over from scratch? Anybody seen anything like this before? Thanks for any help, --Greg
