I currently have an iPad 2 and decided to jailbreak using tAig and Cydia. I downloaded and paid for the BigU. I was previously using Playbox HD to watch movies and use Chrome-cast to display the movies on my tv. I heard the BigU and heard great things so I downloaded and paid for it. After downloading some movies and playing them (which works fine) I tried using the cast option (open in..) and keep receiving an error "no application found to support this type of file". All the files I have downloaded are .mp4 I am somewhat tech savvy but new to the jail breaking game. Any help would be greatly appreciated.
