[mythtv-users] Bad TV picture quality on an HDTV

[Matt Grommes]

I turned Sharpess all the way down and added the denoise3d filter and it 
looks much better. I haven't tried upping the bit rate yet, hopefully 
that helps more.

How does the picture on my Tivo look so good with the same signal and no 
tweaking for so little money?

Thanks for everybody's suggestions.
