[mythtv-users] TV Wonder ugliness

[Joe Votour]

John,

Unfortunately, it's a fact of life.

The compression in the PVR-250 is done in hardware,
and is quite superior to anything that can be done in
software.  Part of the reason for this, is that the
card has a dedicated CPU, while the CPU on your PC is
more general purpose and has more running on it.

That said, you could try using MPEG-4 compression if
you're not already.  I notice a huge difference in
quality between RTJPEG and MPEG-4 on my machine. 
Also, increasing the quality will help out, if you
have the CPU to dedicate to it.

Just out of curiosity, how close are you to your TV? 
I'm about 10 feet away from my 32" TV, and my quality
is quite acceptable (well, except for the existing
line noise) capturing at 640x480, MPEG-4 @ 3000, on an
Athlon XP+ 2400 CPU.  I get somewhere around 40-50%
CPU usage, which I'm expecting will go down once I get
my cable issues fixed.  If not, I'll drop the quality
a bit.
