Yup. It's possible. Not sure about the LG, but my colleague's Samsung can play AVI, DivX and MKV files from a 16 GB Sandisk flash dirve. I guess the best way to confirm is simply to load up an HD video file to your flash drive and plug it in your LCD TV. Then play around with the onscreen menu to check if it recognizes the video files on your USB flash drive. Good luck.
