[mythtv-users] Re: Questionable capture quality from a PVR-250

[brent]

It took me longer to get around to it than I expected but I have tested 
the 3 items as listed in my previous message:

1)  Adding a grounding wire to my cable feed seems to have had little or 
no effect on the video quality.

2)  I connected a DVD player S-video out to the S-video in of my PVR-250 
and recorded some DVD video - it was actually very good - much crisper 
than what I get from recorded cable.  If I could record my cable signal 
with that kind of quality I would be happy as I would be hard pressed to 
discern it from the actual DVD.  I'm not sure what this means with 
respect my PVR card however - I am guessing that the S-video input does 
not go through a tuner however.

3)  I have posted a 10 second recording of some video recorded with the 
following parameters:

bitrate     : 4500000
bitrate_peak: 6000000
Width  : 480
Height : 480

It is about 10 Mb.  Changing the bitrates and dimensions has very little 
(maybe none) bearing on the quality of the captured video. 

The file is here:  http://68.144.68.193/download/test.mpg

In addition to this, I have done some more fiddling with the dnr_* 
settings - I can really not see any change in the video with any 
combination of these.
