So the setup is:
Boxee on ATV 3.0 patched.
Two OSX Snow Leopard laptops connected (one a Macbook the other a Pro)
Both have successfully been connected as network sources on Boxee in the past. Months of hassle-free viewing (after a painful setup)
However came back from Christmas, turned the router, ATV etc back on, and one of the Macs (the Macbook) can no longer connect - it reads "No files found at source".
However the Pro continues to work fine.
Tried removing the Mac as a source and adding it again. Its workgroup name appears in the list of available sources, but upon trying to add the folders, it comes back "Operation not permitted", followed by "No files found at source".
ATV and laptops all running on a static IP and - bizarrely - have exactly the same system prefs in the Network and Shares panel.
REALLY don't want to do a factory restore on the ATV. Anyone else come across this seemingly illogical problem?
