[mythtv-users] PVR-350 Clear & PVR-150 With Static

Wed Jan 4 19:49:51 UTC 2006

In theory, the PVR-150 and the PVR-250/350 are the
same hardware wise for the encoder.  In principle,
however, this is not the case.  The tuner chip is
different (I really wish Hauppauge would have put a
digital tuner instead of the can tuner), and I think
that the MPEG-2 encoder chip is different as well.

These two factors combine to a picture that isn't as
great on my PVR-500 as it was on my PVR-250 or
PVR-350.  It might not be just a hardware issue either
- it could be the tuner definitions in the software, I
honestly don't know.  I was going to do some testing
with the equipment that we have here in the office,
but it is good for digital signals only, not analog.

At this point, I don't have any solutions, but in my
case, the difference between my PVR-350 and my PVR-500
are night and day, but I also have a marginal cable
signal.
