I agree, interlace artifacts all over the place. 

The artifacts I see are not worse than what I sometimes see on sports
events, even directly off-air, no Myth involved.

Remember all of the networks are encoding/decoding and processing, as is
your cable/satellite provider, plus all of the terrestrial links, all this 
in addition to your system. It's a miracle we can see anything at all.

OK, I tried Bob using both xvmc and standard as the preferred mpeg decoder
(normally I use kernal and standard). Once I switch to Bob, the video starts
to shake a lot, like an earthquake is going on in the game. Hard to explain.

But, on the otherhand, the motion is smooth, you just can't watch the game
cause of the shaking (gives you a headache after about 15 seconds). I'm
using an nvidia 7300 on ubuntu feisty. Any other ideas? I have tried all of 
the deinterlace algorithm's and all the preferred mpeg 2 decoder settings.
Any other ideas?

-Thanks

Lets start with the basics.

I assume you have the nvidia drivers installed correctly.
How fast computer?
How much memory?
if you play the files in vlc how do they look on your system (with
de-interlace enabled)?

------------------------
--Nvidia drivers...used the ubuntu guide...but how do i check if they're
installed correctly? I can open nvidia-settings and all looks good. nvidia
7300 once again.
--Computer is core 2 duo 1.7ghz on a new gigabyte motherboard
--memory is 1gb with 1.5gb additional swap
--never used vlc, can i run it from the command line? Also i can play hd
divx files in myth video and they look very great, none of the motion
problems i get with sd analog recordings from my pvr-500. Also, keep in
mind, most recordings are just fine, but it's noticable when i watch sports.
Don't know why.
-Thanks
