This is an embedded device, along the lines of the DBOX2 ?

Adding it directly to MythTV would probably be much easier, especially
with respect to handling errors properly.

The advantage of writing a driver would be that any DVB application
could theoretically use the device and MythTV wouldn't need any
modification. This was the rationale for the USB DVB drivers; in that
case it turned out to be a nightmare to support in MythTV and actually
requires it's own code path for tuning anyway...
