I know this isn't really a PS3 forum but you guys always have the answers and I can't find the solution anywhere else. I've been using Handbrake to convert my DVD's to MP4 for use on my IPad using the AppleTV setting. The files work on the IPad very nicely but for some reason the PS3 won't see them. I have the files on a D-Link DNS-323 NAS with the UPnP AV Server setup. The PS3 finds the server and all of the files on it with the exception of the MP4 files. It sees MKV files (thought it reports they are unsupported), AVI, WMA, etc. but does not see the MP4 files and nothing I do makes them visible. Any ideas?
