Perhaps for TV, but try viewing web pages, or anything else that requires 
smallish text. S-Video is SO much better. I was able to pick up a cable for 
$6 at the local Target store. Don't pay the $1000 they want you to plunk 
down for a Monster cable; it's not enough better to be worth it.

Same here. I asked about this here last week. It's apparently a limitation 
of the 350's video out chip. Or, more precisely, if it is possible, the 
ivtv developers haven't figured out how to do it yet. I'd imagine it's a 
function performed by a chip other than the iTVC15, which is why they 
haven't been able to do so yet.

In the meantime, I'm using the "Run Myth in a window" option, with the GUI 
size and position tweaked accordingly. You can also look into "ratpoison", 
a separate program which will make all of X smaller, to fit the usable 
space of your TV.
