Glad to hear you were able to get the video files to work. While some other formats not listed in the manual may work on the televisions, we are only able to "officially" support the ones listed in the manual.
Thanks for the heads up, however. I'm sure some forum members will find this useful.
When I try to play some m4v video files downloaded from cnet TV copied to my usb they don't show up on the TV until I rename them to MP4. They play very nice in HD!
Does anybody know the people programming the firmware updates that they include that extension to be recognized by the TV?
