I recently tried something in the last week that may help others.... I've been having problems with my C31's for months being slow and not being able to pause on demand... it would take up to 5 minutes to pause, which was the most frustrating part for me. Last Monday, I was reading somewhere about someone having different problems that may have been related to the CCK hooked up... and I also have my HR34 hooked up to Ethernet by the way and disconnecting the CCK. So last Monday when my HR34 locked up and had to do a reboot - I decided to try unplugging the CCK from power and go for a while without it to see how my C31's performed. Once the system was backup everything was working great but I've had similar success for a day or two at most in the past before the slow down issues would return. Well it's been a week now and I'm still having amazing response time and pausing immediately when I hit the button and think the CCK was holding me up, I'm really happy how great everything has been working and how it should be. Since I already have my HR34 hooked to Ethernet, really no reason to hook the CCK back up. I'm really amazed that someone hasn't suggested this earlier or seen this type of problem also. Hopefully this might help someone else out with similar problems.
