At least I now know that it is not just me.  Can anyone else throw any light on this?

Cheers,
Dom

Hi,

i have got a similar problem. I own a DVB-T Twinhan VisionPlus card and it used to work properly under Debian. But for a few weeks the frontend cannot be found or installed for this card. I am not able to get the card back working. Here is the accordingly dmesg output, I am using a 2.6.18 kernel with debian testing:

Linux video capture interface: v2.00
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture

frontend_init: Could not find a Twinhan DST.
dvb-bt8xx: A frontend driver was not found for device 109e/0878 subsystem

I think the problems are connected, but i cannot give you a solution.

Bye
