[streaming] streaming from mpeg card

[Doug Kite]

I am testing with vls running on Debian with kernel 2.4.20, streaming from a Hauppauge PVR 250 card. The client is vlc
running on a Windows 2000 machine. The problem I am having is that the video has "dropouts", or areas where it looks
like there is a loss of signal-blocks or checks that are sometimes just a few and sometimes almost the lower half of the
screen and they come and go.

I can record some video to a file with the record-v4l2.pl script and it does not have these dropouts. I have tried
different bit rates with similar results. Can someone tell me how to start troubleshooting this?

The input is a vhs tape, but even the solid blue screen from the vcr (when the tape is not running) exhibits these same
dropouts.

vls.cfg is shown below (mostly the default one given on the videolan.org website).

Thanks,
Doug
