[mythtv-users] Quality difference from WinTV2000 to MythTV

[Russell Gordon]

I have just setup my second Myth box and I have been recording a lot of
shows.  I also have a Windows box next to my Mythboxes that uses the
default software (WinTV2000) that came with my PVR-250 Rev1.  Having the
two boxes next to each with the same graphics card gforce440mx, same 21
inch Dell FP2001 LCD monitors, and the same PVR-250 cards has allowed me
to notice a lower quality video being recorded in Myth as opposed to
WinTV2000.  I noticed that the default in WinTV2000 was 720x480.
Currently my Mythboxes are set to record at 480x480 at 2500kbps.  I have
read on earlier posts that increasing the bit rate and/or resolution
does not yield that much improvement in video quality.  I have one
channel that is a somewhat noisy and if I record the same show on both
the Mythbox and WinTV2000, the Windows video will far surpasses the
quality of the Myth recording.  It seems as though somehow the Windows
recording is using some filtering to get the noise out. If I burn the
Windows video to DVD in 1 hour mode and watch on a DVD player to a 27"
TV via the svideo input, the Windows recording looks better than the
original show did on TV!  What's up with the outstanding quality in
Windows?  Are there any settings I can adjust in Myth to get to the same
level of quality?  I have also burned a Myth recorded video to DVD as
well and it looks about the same as it did on the Mythbox watching the
recording.
 
Thanks,
 
Russell
