Andrew,

Meridian will only give you a beta release if you have a problem. I had navigation issues when I changed between DVD-A and CD's and DVD's. This required rebooting quite often. Some times my 598 would not turn on and would require a reboot. IR commands from other equipment I have would hang up my 598.

Finally M gave me the beta. It has solved most of my problems. My 598 is much more stable since the upgrade.
