unfortunately I don't know what the solution is (one time it turned out
that the problem was a temporary and neighborhood wide, but it just
happened to commence while I was punching down the distribution block
in someones basement). I've heard that Comcast will provide an
amplifier if one is necesary. <br>

</div>A good way to troubleshoot this would be to either connect
the cable box directly to the feed coming into your house, if possible,
and test to see how it works. If it works fine then you can
re-introduce splitters and amplifiers one-at-a-time and see at what
point your problem re-appears. <br>
</div><br>
Of course that could be a real pain, depending on where everything is
located... You could also replace the suspect splitter with a new
"digital cable ready" one, leaving the amplifier out of the equation
for now, and test to see if that improved your VOD situation. If
it does then you can add the rest back one-step-at-a-time to see if any
other problems are introduced. FWIW, I actually found some pretty
good splitters at Home Depot which work fine for me with Comcast.<br>
<br>
Also, calling Comcast and playing a little dumb might work as well;
don't mention Myth, just say that VOD doesn't work. You may
coincidentally be having other problems completely unrelated to your
home as mentioned previously. Who knows, they may be able to run
some tests from their end and possibly even query your cable box and
find something out that way...<br>

Good Luck!<br>
