I find watching flash youtube in the browser poor - too jerky, too slow. Watching youtube via UKTUBE/MPlayer is PERFECT however! Really good job by the developer. Take a look at it. If you can format your tv streams to be compatible with this program, that would be great. Can't help you with specs - try getting in contact with UKTUBE creator Urho Konttori. All we need is a plain text list of the links to paste into UKTUBE.
Love to watch your site with my N800. Good idea ..:
