If rebooting the machine seems to clear the picture up some, then what
you need is some new(er) firmware from Hauppauge. Just download the
exe, run the perl script on it and be happy. ;-) Make sure you have a
very current version of the ivtv driver too. I find that the 0.1.8
version of ivtv and the pvr250_17_21288.exe firmware works fairly well,
though I have had one hard lock and.

There is a delay because Myth is recording the show and playing it back
simultaneously. This is something that you will just have to learn to
live with, unless the developers figure out someway to shrink the gap.
The delay here is approx. 1 or 2 seconds. Before I installed a newer
ivtv and firmware, the delay was approximately 4 or 5 seconds. For the
most part now, I just watch TV the old fashioned way unless it's
something important enough that I would want to be able to pause it.
This way, Myth can record anything it wishes (unless I'm using the
pvr-250 to watch "live TV") and I can watch what I wish and channel surf
without delays. HTH
