Update issues

Ever since the 8/8 update my CDVR has been very sick. Possibly related, ALL my HDHR tuners are not responding to network pings nor does CDVR see them. The Apple TV client sometimes cannot connect to the server or responds very slowly. At this point I would love to roll back to the previous version if possible just to make troubleshooting a little easier (remove one variable). Anyone else getting trouble from the update?

We have not heard of anything similar from others. The DVR update would not cause your HDHRs to be become inaccessible. Sounds like something is wrong with your network or router. Did you try restarting the router?

Yes, restarted the routers, tuners and even the network switches, PC reboot &c. Oddest is the OTA tuners AND the Prime (cablecard) tuners, 2 of each, all fail to respond to pings though the Setup utility sees them but reports them as disabled.
Thanks for the response. I'll have to isolate one of the tuners from the network and see if I can regain connectivity. Obviously not a CDVR issue.
