I want to put video's on my usb to watch on my F700. I put a few music video's on it and out of 5 only 1 works. The rest of them are choppy and the sound doesn't sync up with the video. Works fine on my computer. Im using a Sony 8GB USB flash drive that has been formated. If you have any idea's how to fix this please let me know thanks

You need to convert them to a certain file type (MP4 I think?).

Also, the video and audio bitrates have to be fairly low, too, when you're converting. (Not sure what the maximum bitrate is, sorry.)
