I have a number if H.264 files I received encoded. Play well on my PCs with Quicktime or DivX. When trying to play on DSM0750 - screen goes blank and crashes.... need to turn on / off button manually for it to reboot. The file extension is MP4.
Called D-Link support and the answer is change the file extension and encode differently -- but not how - AVI was mentioned. But that would loose H.264 benefits. H.264 is supported according to spec. Anybody has luck / experience playing H.264 encoded files successfully on the DSM-750.
