Hello, I've got a wintv nova-s plus (pci), but the diseqc isn't implemented in the driver. I've tried Vadim Catana's patch for cx24123 based cards (didn't work for the hauppauge nova-s plus) but on a closer look I discovered that lnb control is done by an isl6421. I've looked up the specs for the 6421, but this chip seems to handle voltage/tone only. The actual DiSEqC message has to be entered via an input pin of the 6421. RANT: Specs for the nova-s plus / cx24123 seem to be top-secret Any suggestions or have I to wait until some kind soul (Steve Toth?) with deeper insight does the work? Regards, Horst
