Description Mark Clarkstone 2014-01-20 17:00:16 UTC 
= First time bug reporting so please bare with me! =

I have a Tevii S471 that I use to receive Astra 28E here in the UK using the newer TS2020/DS3000 driver [I'm not sure what version it is, but the ds3000.c code is different in older kernels], the card tunes to the wrong transponder when tuning to the frequency 10818 V 22000 5/6 instead of receiving the services BBC THREE, BBC News etc I receive the services on transponder 11343 V 27500 2/3 CBS Drama, News 18 etc.

I've been doing a bit of testing and using an older kernel (3.7.4) with the older driver the card returns the correct services for the above frequency.

Here is a screenshot showing my two tuners returning different services for the same frequency (the cards are using the same dish) http://postimg.org/image/rfwsu2ta3/full/ (this is using the newer ts2020/ds3000 driver) and here is what the older driver returns http://i.imgur.com/pNrK0NJ.png

Apologies If I'm posting this in the wrong section, please feel free to correct.

I can confirm this behaviour with the s471 driver on linux-3.12.7 and the same transponder.
