I'm having a very strange problem with one of my jailbroken iPads. It's an iPad 1 on 4.2 using snowbreeze jailbreak. I synced it with iTunes tonight adding some video apps as I use this iPad primarily as a small bedside entertainment device. Since I did this sync, I am unable to play YouTube videos...when they are in an external app. I can play a video in the Apple YouTube app, I can play a video in safari, but if I attempt to open a YouTube video in Videohunters, Showme, Squrl, etc any app that acts as a video aggregator I either get the play symbol with a line through it or a message that states, "the video has failed to play". I've reset the network, rebooted, respringed, synced, and uninstalled and redownloaded the offending apps. I can play other video services like Vimeo fine. The same apps work fine fine my iPad 2 (though I'm too nervous to sync it). Can anyone offer me a lead? This iPad I could restore if absolutely necessary but I would hate to.
