Errors with vlc and pvr250

[km]

I'm testing multicast udp streaming with the ivtv driver
and vlc.

If I just capture a file from /dev/video0 and stream the file,
no errors.

If I stream /dev/video0 I get a fair number of errors from vlc
of the form

[00000190] access_output_udp private debug: mmh, paquets in the past ->

Any idea what the problem is?
