A few people have tested it out too without hitches.. In fact i worked upon to have zapping inside ca_zap itself such that one needs not do a scan --> szap --> ca_zap, but just a scan --> ca_zap would be sufficient. But just to remove the bugs and other issues i have that part temporarily removed, but can have that part also into it .. BTW, just to avoid duplication, i have been factorizing code, such that at the moment i have a small library in which there is a small set of routines that parses channels.conf for DVB-S/C/T.. Another part that i factored out was the filter setup.. I thought i would finish those and send it, but the recent posts regarding the driver led me to have a look at the driver again.. ( I have some patches ready for people to start testing it out. I will post it a while later in the night).. Manu
