[mythtv-users] Diagonal "waves" on tv display

[Jonathan Guthrie]

When displayed on CRT monitor or on a different machine's frontend  
LCD, the "waves" aren't there, so I am assuming it's not on input,  
but on output from the display card to the TV. It's going out via the  
svideo tv out on the nvidia card, with a svdideo->composite adaptor.  
This is not shielded.

So are you suggesting that's where the problem might lie?
