Have you try it with the Jensen? If it doesn't work then you are out of luck. However, you might or could get a media player that might support the video file that you have now. A media player will support a lot more formats than your LG can.
I've got a 16gig jumpdrive with some movies, and it playsthem on our LG dvd recorder/ player but would like to play them in our new camper. the camper has a Jensen cd/dvd player with a usb port and a 3.5mm input jack aux/a/v in. my question is there a software player that will play these movies thru the usb port? the movies are avi files.thank you for any assist
