Didn't know where to put this, Sorry.

I have installed version 0.3.2z and it does work save
for the mpegs play in fast forward. I'm no expert with
this kind of thing but I believe it is the audio that
is not captured right and the video is simply trying to
keep up.

I did manage to find a work around. While capturing
using cat or similar reload the firmware using ivtvctl
-H the video will return to normal. I've tried hacking
the code and placing the firmware reload during
openning of the device and reading no success.

    I was experimenting with an upgrade to kernel 2.6.12.5 and
    my trusty old 0.2.0-rc2k ivtv source I used with my
    2.4.28-gentoo-r8 wouldn't compile, so I tried ivtv 0.3.3 .
    When I got the machine rebooted, I experienced much the same
    problem, except I had it through live TV.

    The audio was very choppy. If I paused the live TV, the
    buffer accumulated at something like half-speed. It would
    take maybe 10 seconds to accumulate 5 seconds of buffer.
    Then when I unpause it plays back at double speed, the audio
    sounding like timestretch x2.

    I have since switched back to 2.4..28, and live TV doesn't
    malfunction.

    His ivtvctl -H appears to temporarily solve the problem for
    me as well. Unfortunately, exiting live TV and re-entering
    live TV reactivates the doublespeed stupidity. I assume
    this would plague every recording.
