Kworld DVB-T 100se not working in Ubuntu 10.10

Asked by Graeme Lanham

I have a Kworld DVB-T 100se PCI card. dmesg reports:

 dmesg | grep frontend
[ 12.634948] cx88[0]: subsystem: 17de:08a1, board: KWorld/VStream XPert DVB-T with cx22702 [card=43,autodetected], frontend(s): 1
[ 12.847813] cx8802_alloc_frontends() allocating 1 frontend(s)
[ 12.852396] cx88[0]/2: frontend initialization failed
[ 12.983169] cx8802_alloc_frontends() allocating 1 frontend(s)
[ 12.984095] cx88[0]/2: frontend initialization failed.

I have read reports that this card should work out-of-the-box for 10.10 but certainly doesn't for me.

Have not been able to tune on any live TV viewer, MythTV, XawTV, Kaffeine, etc.

What am I missing?

Ok you should look for guides on:
Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)

This is what the chip used is.

I had previously come across this site (http://stevepugh.co.uk/mythtv/). It's contents are somewhat problematic for my purposes. Firstly, it refers to Ubuntu 6.06, secondly, if refers to a completely different TV card (albeit with the same Conexant chip) and lastly, it refers to satellite capture rather than terrestrial.

I keep getting drawn to this page: (I'm sorry, but I can't figure out how to hyperlink in Firefox)

http://www.linuxtv.org/wiki/index.php/DVB-T_PCI_Cards#KWorld

which indicates that the card in question is supported in linux.

I have been trying to get this card working in Ubuntu for the last week or so, but all of my research turns up gobbledegook involving pages of code that has no real meaning to the lay-person, like myself. Please prove me wrong, but it seems to me that Linux will never be a real competitor to Micro$oft in the world of operating systems until it becomes a lot more user-friendly.

Can you help with this problem?
