Strange that things work in 2.6.19.2. And with the polling config in 2.6.20. The DVB-T card is the only one I can test now, it works well; in fact the only restriction is the reception quality besides the network and DRM. The DVB-S card has not been used once. It was just plugged into the system. Does it need firmware like the DVB-T card? 2.6.19.2 shows at bootup: saa7146: register extension 'budget_av'.

The EN12000 is equipped with a PCI riser like the one here: http://www.tranquilpc-shop.co.uk/acatalog/info%5f2%2ehtml Please also see http://www.tranquilpc-shop.co.uk/acatalog/PCI_Risers.html and http://www.tranquilpc.co.uk/support/Files/TPC014/Tranquil%20Riser.pdf for info about how the riser works.
