I don't know if this will shed any light on your problem. I have found a bug in the neutrino uk02 image.
I was trying to delete a channel from a bouquet (from the dm, not from the pc) and my box went into radio mode. It got stuck in that mode so I rebooted, after the reboot I noticed the box had lost all my channels and bouquets. The only channels I could get were in radio mode.
I reflashed my dm and everything was ok. So I tried deleting a channel again and exactly the same thing happened.
So another reflash and all is ok again.
Maybe you found the same bug as me hopefuldreamer or maybe you found a bug of your own. Either way, reflash your box and you should be up and running again.

The direct file record doesn't work either, just fails with an error message saying unable to write. Yet you have to mount a fileshare from your PC just like you do to play back files.
Maybe these two problems are connected. I know in my case there is nothing wrong with the mount because I telnet'd onto to dreambox and copied files to the mounted fileshare so I know it works. The problem seems to exist with the neutrino software somewhere.
