Thanks for the patches. ¿Is your lastest unified diff on your page (a700_full_20080412.diff) equivalent to these patches or must they be applied separately?
I'll try to some tests tonight, if you have made some progress. By the way, ¿could you tell me if it's better to use use_frontend=0 or 1 for saa7134-dvb module? I think that this changes the driver used for frontend, but I'm not sure.
Regards,
Eduard
