Hi, I received my new U5 today. When I play anything from my iptv provider through Buzz tv 5 it stutters. When I play anything with another app. from the same iptv provider it does not stutter . Also I cannot record anything, the app says recording but when I try playback of the recording it give me an error message. Note I put the included hard drive in the U5 and formatted it . Any help would be greatly appreciated,
