as a linux users with a good background in security I do update and upgrade my mythbuntu box on a regular basis. Even if it's an private LAN - there are more vulnerable clients in the same LAN and they could be used as a hop to attack the mythtv box.
So, after a nice
apt-get dist-upgradeto migrate to mythbuntu 11.10 I suddenly had Kernel 3.0.0 in use. Bad karma for my two lovely, rock solid Technotrend S3200 DVB-S2 cards. Both cards could not lock on a transponder anymore, LiveTV was gone. Within the status field on mythfrontend the transponder status became
Tl__for about 15 seconds and then mythtv complained about a missing lock.
According to http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-budget_S2-3200#Card_only_rarely_locks_onto_any_transponder this is a known bug. Comments about the TT S3200 card were bad and I was not in the mood to re-compile a stock mythbuntu kernel.
So I searched for alternatives and found the http://linuxtv.org/wiki/index.php/TBS_6980/6981 TBS 6981 card, judging by comments the best DVB-S2 card available. And it has a PCIe interface and twin tuners - awesome!
Purchased on Amazon, delivered next day. Installation quite straightforward:
- Copy linux drivers from http://www.tbsdtv.com/english/Download.html
- Transfer to mythtv box into /tmp
- mkdir TBS6981 && cd TBS6981
- unzip ../linux-tbs-drivers-111118.zip
- tar -xvjf linux-tbs-drivers.tar.bz2
- cd linux-tbs-drivers
- ./v4l/tbs-x86_r3.sh (for I32 Kernel 3.0.0)
- make install
Best thing: the new TBS 6981 card is way more sensitive than the Technotrend S2-3200! Signal quality increased from 2% to 76%, SNR ratio from 2.0 dB to 4.8dB. What a good buy!
If you wonder about the small numbers with the TT S2 3200 card - I am using a tiny Selfsat dish.
Summary: Perfect card. Ultimate recommendation.
