I think you need a newer version of bttv-0.8.x. The G_PARM fix went in

OK, I backported the G_PARM fix back to 0.8.33 because I don't want to
have to get into building my own kernels (I just don't have the time
to get into being a kernel maintainer too -- I will upgrade to the
latest bttv 0.8 when my vendor releases a 2.4.19-pre8 based kernel).
NUVrec now runs and records but the sound is "accelerated" (i.e.
sounds like Alvin and the Chipmunks) and out of sync. Here is the
output from NUVrec:

Keep in mind, I also commented out the code in
nuvfile_core_overrides() that overrides any -r parameters and changes
the value to 44100 -- I just wonder if that's there because the NUV
codec has to have audio sampled at 44100.
Yup. If you comment out trhe code, it will record at 3200, but still
play bakc at 44100! (the file format does not specify playback rate)
