First of all: best YouTube client for the N900 so far, thank you.

Secondly: I'd say it would be more important to have that software buffer you talked few posts ago than full built-in player. So far I haven't found a single video which would play "watchable" buffering (I get "buffering" messages every two-four seconds).

cuteTube + KMplayer would be ultimate combo if the buffering issue could be resolved.
