Hi Markus, I have finished to try v4l-dvb-experimental-userptr version and now the driver seems to be loaded well, as you can see in dmesg

However neither the stable nor the experimental version work in this moment with kernel 2.6.20 I hope it can be useful for the driver development Thanks a lot for your support, Valerio
