Yeah, that's what I've been doing. Seems like the azbox needs a reboot every now and then. I've found out that if the time is not set correctly, recording is problematic beyond the obvious. For instance, you set the clock a couple minutes off, a reserved recording will not finish - display looks like it has - and the box is sort of locked up. It will respond to the remote, you just can't see what's going on on the tv. I have to reboot every time. I've telnet'ed in before rebooting and looked at the files in the recordfile area. It will have a bunch of .idx and a few other files which are orphaned after reboot.
Also, if you set the time manually, use the 24 hour format i.e. 13:29 vs 1:29 pm. If you set the hour and minute and then go back and set am or pm, it screws up.
