Hi all, i got problem. I'm using GT2710 dan Q03UDE PLC. I want to play *.MP4 video from internal SD Card attached to GT2710.I already create special function switch and chose video playback for filename 1.MP4 stored on root of sd card. But the video wont play at all. Only switch to play video screen and note on the bottom "This function cannot be used right now". What should i do? I already re-decode the mp4 with simple MPEG-4 as written on mitsubishi manual. Please help.....
