I am not in a position to test the attached patch at this time.
However, a couple of months ago, when I was looking into the problem,
I found that lowering the timeout for read errors from 2.5 seconds to
1 second allowed LiveTV to recover better from glitches.  The attached
patch makes that change.

Here is a link to the driver patch that will *probably* make this
change unnecessary:

Q: Why is top-posting such a bad thing?

This patch appears that is may be a kernel module or something like that
and not a part of the standard git download of mythtv.
Can you point me to a wiki on how to install the patch you provided?
