You probably would see a drop in quality moving to component, though it will
depend on the converter and the TV. With my plasma I can see a difference
between VGA and DVI and component will be worse than VGA (though it may not
be noticeable).

I don't think you'll be able to feed a 1360x768 signal to the TV via
component. I'm not sure how the converter will handle it but I imagine that
the TV will be expecting a "TV" resolution - 480i/p, 576i/p, 720ip, or
1080i/p. Check your TV manual.

You should probably just try it unless the converter is expensive. Only you
can say whether the drop in quality is worth the convenience.
