Strange DVD rip playback issue from Windows 8 Storage Space share

I have a PC running the Windows 8 release preview. I am attempting to play back a ripped DVD (VIDEO_TS folder from DVDFab) via Windows Media Player on a networked Windows 7 PC and am getting some strange behavior:

1) I ripped the DVD to a share in a "Storage Space" (3-drive with parity) and when I try to play it back on the Win 7 PC I just get a blank screen.

2) I copied the same rip from the Storage Space to a share on the Windows 8 boot drive and it plays back fine on the Win 7 PC.

3) I converted the same rip to MKV and placed it on the same Storage Space share and it plays back fine as well.

Anyone have any idea why I am having trouble playing the rip from the Storage Space share? It doesn't seem corrupted and the share seems to be set up properly. Thanks for any help.

Thanks for the idea but unfortunately I have the same problem with the mapped drive.

I did read about the drawbacks at this blog post and they are acceptable to me as long as there is no catastrophic data loss. I am just testing now and do plan to wait until the release to put all my movie rips on there but with this strange playback/sharing problem it is not a good start...
