    Video Capture Card no longer working

    I've got a mythtv setup and am using 2 digital capture cards and an analog, all of them have been working fine for a little over a year.

    just recently the SCART - RCA cable going from the foxtel to the Haupagge PVR 150 card stopped working so we went and got a new cable. All working fine when i plug from Foxtel - TV, but when i plug into the mythbuntu box i dont get any pictures.

    I tried using VLC to stream the capture card "/dev/video0" but it just crashes with no error.

    I checked the kernel logs and this is what show up, anyone got any ideas?

    /var/log/kern.log

    Code:
    Jan 23 13:18:07 media kernel: [  608.947625] ivtv0: All encoder YUV stream buffers are full. Dropping data.
