Hi Jamie & Manu,

Last night I tried to get the DST working as well.  I've got a VP-1020 
DVB-S card.  This is my first time playing with kernel modules, so 
please check my sanity/order-of-operations:

1.  Downloaded and configured linux-2.6.0-test9 kernel
2.  Did a CVS checkout of dvb-kernel
3.  Ran the "makelinks.sh" script and pointed it at my kernel
4.  Ran "make xconfig" and selected pretty much everything in the 
video4linux / DVB section (specifically enabled DST).
5.  Compiled the kernel with "make bzImage ; make modules ; make 
modules_install"
6.  Configured grub with a menu option to select the new kernel
7.  Booted into the new kernel.

How does that sound?  Am I missing any steps?

Where I'm at right now is if I try "modprobe bttv", it'll hang my system.
If I follow the instructions in the dvb-kernel's README.bt8xx, I see 
that I'm supposed to make a little "insmod" script.  So, I copied 
build-2.4/insmod-bt8xx.sh to insmod-dst.sh, and edited it to select the 
DST drivers, but when I try to run it with ./insmod-dst.sh start, I get:


Inserting DVB modules into kernelinsmod: can't read 'videodev.o': No 
such file or directory
insmod: can't read 'bttv.o': No such file or directory
insmod: can't read 'dvb-core.o': No such file or directory
insmod: can't read 'v4l1-compat.o': No such file or directory

insmod: can't read 'video-buf.o': No such file or directory
insmod: can't read 'dst.o': No such file or directory
insmod: can't read 'bt878.o': No such file or directory
insmod: can't read 'dvb-bt8xx.o': No such file or directory


Do I need to be in the /usr/src/linux-2.6.0-test9/... directory tree to 
run this script?  Am I missing something?

Thanks,
Grant
