Subject:    [V4L] Poor cable television reception and dropped frames

I use vcr to capture television programs with a brooktree tuner/capture
card.  It seems that the channels at the lower end of the spectrum (ie
2,3,4) have poor reception due to bad in wall cables.  When I do
captures on these channels drop lots of frames in an hour. Channels at
the higher end of the spectrum do fine.

Machine is a dual P3 933 with 1 gig of ram, and 170 gig of ATA 100
7200rpm drives.

Capture thread exiting
         Captured 111504 frames.
             Frames dropped in capture: 652 (0.0%)
             Frames dropped in encoder: 1191 (0.0%)

         Total Unfree 3596428 bytes cnt 49 [0,0]

Can anyone shed any light on if this is an expected behavior?
