I have a YESS DVB-T4688U (bought Feb 2010), and want to play movies from the USB, or copy movie files from the USB to the internal HDD, and then play them.
I can see JPGs and MP3s but cannot see any movie files that are on the USB memory stick. I have tried .TRP and .TS, as well as the more obvious .AVI, .WMV, .MPEG etc.
Also, copying recorded programs from teh HDD to USB does not give me anything I can access on a PC.
