media software/navigator on the TViX A6500M !??
Plex only works on Intel Macs with Mac OS X 10.5 (and partially 10.6).
If you have such a Mac, and your TViX supports some kind of popular sharing protocol (like SMB for example) then you could mount the TViX on the Mac and use it as source.
It works very good with Synology products. I have the 409+ and it works like a dream (well at least after hard entering the user and password in the "sources.xml" so I do not have to manually enter them every time I want to use those sources).
