[mythtv-users] Quality of recordings degraded

[John OKeefe]

I just got my MythTV setup working and it has been up and running for almost
two days. The recordings have been great so far. Then this morning it
recorded a show and the quality of the recordings has degraded. This also
happens in LiveTV. Specifically I am getting some slight noise and some
transparent blue vertical lines in the picture. I have watched the shows on
the T.V. without the MythTV box and they look fine so I know it is not the
signal from that Satellite receiver.

I was looking at the recording profiles last night but I am pretty sure I
did not change any settings. Could changing the recording profiles i.e. bit
rate or recording type affect the recording/LiveTV like I mentioned above?

Any thoughts on what is causing this?

Is the box getting to hot and that is affecting the picture? Is that
something that typically happens? I am not at home right now so I am unable
to check the box to see if it is hot or not.

Here are my system specs:
KnoppMyth R4V4
P4 1.4 Ghz
PVR-250
120GB Maxtor 7,200 RPM hard drive.
512mb ram
AC97 On board sound.
Elite P4VXMS motherboard.

Thank you for any help in advance!
