Hi, Even after installing linux-s2api-tbs6921_v1.24.1.rar without errors, the card does not show up in my MythTV Backend Setup.

I have a 64bit Mythbuntu 10.10
Kernel:- 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux

And yes I executed tbs-x86_64.sh before make && make install.

some output

hi, the above error message means that the driver doesn't load successfully and that's why DVB applications like MythTV can't see the card as installed. unfortunately, the above error message is most probably due to fault in your TBS 6921 hardware. please, provide the output of "dmesg | grep tbs6921fe". thanks.

Sorry it took this long to reply but the problem is sorted out.

I unplugged a DVB-T usb stick connected to the machine, reinstalled the drivers then rebooted and mythtv can now see the card.

Here's your output though
@htpc2:~$ dmesg | grep tbs6921fe
[ 30.163799] tbs6921fe: software version is 1.24

I wish to point out that the card works well on win7 plus I can watch TV with kaffeine on the same Ubuntu machine.
Now i just have to get correct settings for DiseqC on mythtv.

Thank you for your trouble.

no problem, it's all's well when it ends well.
