I tried "i", deinterlacing with 1 and 0, no difference, may be you know the 
running information text on the bottom of the screen from NTV, it is not 
possible to read them. (Unfortunately with WIN 2000 on the same machine they 
lock quiet good).

you are right, there are channels with better and lower quality, but I do 
think there should not be a big difference between Win2000 and Linux.

CPU is used by 10 to 15 % max.

I looked at the sources, (.../dvb-kernel/linux/driver/media/dvb/b2c2), but I 
am realy not shure how to enable the debugging. I tried to modificate the 
skystar2.c (static int debug = 0, 1 and 2), but I have never seen any 
difference.

so I tried 
make clean
./getlinks
make -d
make -d install

I added the results od 
lsmod
dmesg
lspci

but this results in 92964 lines. As I don't believe, that you are realy 
willing to get this kind of information, can you pleasy specify how I can 
produce the information you need.

I don't get errors during make, but during make install
