Yup, there certainly are some glitches left. For me it only works if I do 
everything in a certain order, i.e., dec must be switched on and running 
before I load the kernel module. It also doesn't like the usb-uhci 
interrupt to be shared with my network card (I have to ifconfig down 
eth1). Sometimes the video stream appears to be corrupt, the video looks 
horrible and mplayer complains a lot, otoh the audio is still fine. I 
also have some tuning issues but am not sure whether my channels.conf is 
fully correct.

Also, some of the common tools (tzap, dvbtune etc.) seem to silently
assume a fully featured (not budget) card and try to setup streams that
the dec does not deliver ? Which programs are you recommending for tuning
and playback ?

see attached. Somehow it seems to boot, disconnect, boot again ?

I had made an update over air (I am living in Berlin, Germany) and it says 
software version is:
 DEC2000-t Ver 1.05de
