I've been scouring the Internet looking for help with my problem.  I found a
posting at:

http://www.spinics.net/lists/linux-dvb/msg29645.html
...I swopped-out hard drives and installed Mythbuntu. After installing the
cx18 drivers it also only initialized one card. I then modified the
bootloader with "vmalloc=256M" and it worked like a champ. ...

I'm not sure where the bootloader is located and how risky it is to edit so
I continued searching for information on editing the bootloader.  I couldn't
find anything.  I have a 640GB hard drive.

I also ran the suggested command, "cat /proc/meminfo | grep Vmalloc" and got
the following results:

VmallocTotal:   114680 kB
VmallocUsed:    101208 kB
VmallocChunk:    11764 kB

Can anybody give me guidance on the steps I need to take?

Thanks,
Greg
