Strange, for me ruDbox 1.24 works very well, I've never had a hang when switching channels yet, suppose there is some diffrence on these boxes too as it seems to be with DB
Regarding how to start the cams in ruDbox there is a simplier way then to telnet to the box, just press menu-0 on the RC (button Menu and numeric button 0) to restart current cam, menu-1 to start mgcamd, menu-2 to start evocamd, menu-4 to start newCS
This starts the corresponding /var/scripts/menuX.sh
