ECF, I have found that the only time FF and RW will work with media loaded on the DSN-321 is if it is the DVR-MS format via MCE. From what I have been reading this is an issue with MCE. I still cannot get Media Lounge to see the DSN-121 so I don't know if the same problem would exist. I loaded an AVI to the computer and ran it using Media Lounge (which does see the shared WM folders on the server computer ony) via WMP and it worked fine. So to recap: I cannot get the DSM-750 to see the DSN-121 and run files via the Media Lounge. Using MCE it does see the DSN-121 but will not FF or REW unless its a DVR-MS format. I cannot get media lounge to find any files anywhere. Its looking for a molder called "MEDA_Share" and I have no clue to its location. Sadly, my next step will be to format the server computer, and reset both of my DSM-750's and start again fresh.
