I have found a solution for this problem. According to the IVTV website, we should be using the kernel modules given the fact that we are using the 2.6.15 kernel lines. After searching the kernel modules, they are all rename to *.ko.saved. I mv the following modules back to .ko in the following directory:
cd /lib/modules/`uname -r`/kernel/drivers/media/video/
mv msp3400.ko.saved msp3400.ko
mv tveeprom.ko.saved tveeprom.ko
mv tuner.ko.saved tuner.ko
mv saa7115.ko.saved saa7115.ko
then I did the following:
cd /lib/modules/`uname -r`/extra
mv msp3400.ko msp3400.ko.old
mv tveeprom.ko tveeprom.ko.old
mv tuner.ko tuner.ko.old
mv saa7115.ko saa7115.ko.old
depmod -ae
I rebooted simply basic I can not figure out how to remove all of the required modules, as described on the ivtvdriver.org website
Now I have a work MythTV Box again.
