I've only experienced this since I started running FroYo on my Droid.
I cannot upload videos larger than 1GB, obviously (and yes, I am on wifi). The weird thing about this is that there isn't a video I've recorded that is larger than 195mb and I receive "You cannot upload videos larger than 1GB" when trying to upload them on YouTube via the app... any pointers? Tips? Anything to fix this? Is anyone experiencing this as well?
