Couldn't be easier.....
Two options
1) Install the Dvico netshare app (remember to use remote desktop to launch). You need to configure Netshare and point it to the directory that contains your files. I always call my share tvixhd1 (not sure if that is strictly needed any more but better safe than sorry) Configure the 6500 to use NFS and give it the IP address of the WHS and the name of your share
2) Configure your media files directory in WHS as a 'share' and allow public read access. Then go to the 6500 use SAMBA this time and point it to the IP address of the WHS and the name of your share.
Couple of points....
A) I would suggest you do both of the above. Although both NFS/Samba work fine for Hi-Def I find some ISO's work better on NFS and some AVI files work better with Samba. You have four network slots on the 6500 anyway so just use two of them
B) Netshare is an application not a service. That means that if the WHS reboots then it will not be launched. To launch you remote desktop to the WHS (at which point it starts) then close the session. Netshare will continue to run in the background.
For example MS applied an automatic patch this week and the WHS rebooted to apply it. Therefore I lost NFS until I rdc'd back in.
All in all though it will work great.
Hope this helps.
