I use the AllShare Cast Dongle with my Note 10.1 (2014 edition) also my S3 phone. With the Note I am to mirror all my screens on a large screen tv with no problem. The only thing I cannot get to work is mirror movies downloaded from Samsung Hub. Sometimes I get video only and no sound an other times nothing. My S3 phone works but I don't want to download movies to my phone rather have them on the tablet. Cannot find any documentation on the Samsung web site. Any suggestions?
