Here is a patch to limit the mythtv bps used for seeks to a reasonable
value. It has been tested and appears to work.
The basic problem I was having is that some audio converted ATSC video
from a couple of stations appear to somehow cause very high Bps's to show
up and when used for seeks result in incorrect huge seeks.
Here is sample output I have from one of those ATSC recordings that have
the issue:
Seek Bps was 2835 kbps
Seek Bps was 3726 kbps
Seek Bps was 0 kbps
Seek Bps was 3164 kbps
Seek Bps was 80436 kbps too high - set to 4Mbps
Seek Bps was 4195 kbps
Seek Bps was 3140 kbps
Seek Bps was 0 kbps
Seek Bps was 0 kbps
Seek Bps was 3179 kbps
Seek Bps was 3406 kbps
I don't know where the 80kbps came from, the OSD is also showing similar
high numbers but does not cause issues.
