Software analogue cards have been dropped, dvb cards are still there dont worry (digital cards are considered software because dvb stream is already in mpeg2 form and so doesnt need an encoder)
I've had the same problem, although my FlyDVB-T card in another box still works perfectly.
Anyhow, the reason the TechnoTrend / Hauppauge DVB-T card doesn't work is because a new Interop.TunerLib.dll file with date 21/11/2005 has been updated into the CVS.
You need to copy the old Interop.TunerLib.dll dated 01/01/2005 from the original distibution into your MediaPortal directory...
Once done the technotrend will work again
