I think the improvements people reported when switching to 2.6.20 are 
showing that there was at least some part of the problem is related to the 
hcd-driver in Linux.

It seems that there will be some in the close future to work on linux-dvb 
again. I will then release a new firmware for the dib0700 and at least 
everyone has something to test.
