I had ATT dsl and was streaming mp4 files from my pc to a Sony 370 bluray over ATT 2wire gateway. Switched to Suddenlink cable for faster internet and have tried a Linksys E2500 and a Netgear 3700 router and cannot get bluray to play the same files. The bluray sees the folders, but when I try to play them it says corrupt or un supported files. Any ideas how to fix this?
