please try to change file DVB/driver/frontend/alps_bsrv2.c at line 134
from

 u8 buf [4] = { (div >> 8) & 0x7f, div & 0xff, 0x95, (pwr << 5) | 0x30 };

to

 u8 buf [4] = { (div >> 8) & 0x7f, div & 0xff, 0x95, (pwr << 6) | 0x30 };

and report if this fixes the problem. (this works quite well with my card.)

hope this helps,

andreas poethke.
