I just got the 32Gb TP yesterday, and copied MP4 files (the entire "Firefly" series :-) ) to the TP from my Pre. They show up in the TP, but without names or any details other than the running time (!). So I can only choose whether I want to watch the 43:17 episode, or the 42:24 episode, etc.?
Any ideas? I tried renaming them on the TP, through the USB connection, but it didn't change anything.
