Yep, I couldn't agree more. I have a brand new XBox 360 with a 320GB hard drive, and it seems like every time I open the Youtube app it takes less than a minute to take the whole system down (the TV screen goes black, and then displays "No Input", and the XBox has to be turned off at the console to get it to come back up). It's a total mess, and while it was a cool idea, the XBox 360 just doesn't handle this well. I don't know if it's the new XBox 360 or the app (my last XBox 360 worked like a charm - never had a problem with it, but wanted to upgrade to something larger than a 20GB hard drive), but either way, the XBox 360 fails to deliver.
Maybe the PS3 version will be better. It already handles media much better than the 360, so I'm hoping the app has enough of the bells and whistles so that I don't even have to turn the 360 back on unless I'm going to play a game...
