HR34 Can't Access SOME shows on whole home

Noticed something strange this weekend trying to access shows on one of my HR20's from the HR34.

First of all this HR20 has some problems and I have to frequently reboot it (every couple of days) in order for any of its shows to be present on the list of any other DVR (not just the HR34) or I get the red circle with line through it indicating that the show is playing on another DVR for every show on the problem HR20. Rebooting will fix this problem for a day or two. After I finish watching all the recordings on this HR20 I am going to deactivate it since the HR34 will more than replace it.

This weekend, I was trying to play a show from this problem HR20 on my HR34 and I couldn't. I tried to access it through my HR24 and saw the same thing, so I rebooted the HR20. After reboot, most of the shows from the HR20 were available from the HR34's list, but a few of the recently recorded ones were not. I looked on my HR24 and the recent shows were their and I was able to play them. I rebooted the HR20 again and I still wasn't able to see the recent recordings on the HR34. Has anyone seen anything like this on their HR34?

thanks,
Murray
