[mythtv-users] Re: 1000th picture quality question

[Howard Cokl]

I have the same problem.  Currently have a freestyle
card, which is itvc15.  I just ran a test and it
appears that if I cat /dev/video0 >
/store/video/test.mpg and let that run for a while and
then watch it using the Mythvideo it is closer to what
I get when I watch TV connected directly to my DirecTV
box, but it's still not as crisp.  I am trying to
compare the PBS logo since that is unchanging and
gives me a point of reference between switching to all
the different views.  Basically, in DirecTV to my TV
the logo is smooth, no jagged edges at all, and with
Myth all of the edges look jagged.
