As you can see from my other post, the PS3 cannot decode VC1 but the WDTV device can. So I loaded the WDLXTV firmware hack (from B-Rad), ensured the NFS app bin was loaded and tried to xmount an NFS share from the MBWE via USB ethernet. Every combination I tried with the net.mounts file showed nothing in any folders. It is making me fairly mental.
Has anyone tried this yet? The WDTV can play just about anything I throw at it (sure it has some subtitle issues and FF and RW suck a little bit but it plays DTS audio).
On a good note, I am copying data via windows using NFS now and holy crap am I happier.
