Scaling up to any of these resolutions gives me a fairly pixelated picture with blurred lines -- pretty much what you'd get if you took a jpeg and enlarged it with ee, or some similar tool. This seems predictable to me -- what else would happen if you blow up a low resolution picture? The part I don't get is why it's such a sought after feature. Is there some way to enlarge a low resolution source without making it blurred and pixelated? When doing fullscreen from a bt878 card, I set fullscreen to 640x480 in ~/.xawtv. b.c.
