They are broken for what I do say during the last three months and a
build just now tells the same.

Your card should at least support Australian DVB-T HDTV.
We have some new support for DVB-S in 2.6.26, mostly triple or quad

more feedback here for HDTV usage. (not S2, but for example BBC HD
1080i, works flawlessly somewhere else ...)

We have much less testers than previously I believe.
The tda827x still seems not to compile, if tuner customization is not
