Hmm.. The CU 1216 is a DVB-C tuner, whereas the MB86A16 is a DVB-S/DSS
DC receiver

It could be that NO SIGNAL for the relevant frequency what scan is
requesting to tune to.
I didn't follow what you meant by module shuts down.
I think all you need is a proper initial frequency list. If your
frequency list has invalid frequencies, you will see NO SIGNAL 's in the
logs. :-)

I don't understand the problem. I can rmmod mb86a16 and do a modprobe
mb86a16 without any tuning issues.

You wouldn't need this change, it is asking the DMA to use the software
filter for a 188 byte stream whereas you have a 204 byte long stream.
Wouldn't hurt much , except that you will get a garbled stream.

You wouldn't need this change for the MB86A16, wouldn't help at all.

You need to have a bit of patience. :-)
I wouldn't want to recommend any hardware, whichever one it is. The
Mantis drivers that what you are using will be the official Linux
drivers from the vendor (Azurewave (a new fledgling company part of the
ASUS group), formerly known as Twinhan). :-)
