Natively, no. Jailbroken, maybe (don’t know of a specific plug/source that does it yet).

tinytube.net (Safari browser) will allow you to stream video via a proxy server from several streaming media sites, including google video. The proxy converts the original media into QuckTime before it is streamed to your iPod Touch.

just download the video if u havnt already, then convert it to mp4 and put it onto ur iPod touch (not itouch) via iTunes. and no, there isn’t any app u can get with jailbreaking that will allow other video formats.

@bassist_king_1: I thought so (re: the jailbreak app not available) thanks for confirming that.

yeah i did it and it worked for 1 time and i cant get it to work any more, i must be doing something wrong , but yeah you can do it
