Recent PyTivo and VidMgr Problem

I am having an issue I have not had in the past and it is bugging me. I am wondering if it has anything to do with the latest Tivo update. Seems that the share becomes inaccessible on various Tivos from time to time (I see the share at the bottom of "My Shows", but it returns that it is empty when I select it.

Or, using VidMgr also at that time will return a V301 error to try again later. This will happen on one Tivo (I only use premieres for this) and work just fine on another. A reboot of the offending box fixes the issue.

Any input on troubleshooting?
