Inherited an old tv - JVC-lt32da30j. It comes with a USB port and does play Mp4 ripped from DVD, but won't play other mp4 formats such as file conversions. It'll play mpg but these are taking up a LOT of room on my drives. Looking for a manual in the hope it'll give me some idea of the mp4 format it prefers. Up to now I've been doing a lot of trial and error conversions. Getting bored with it all now.
