[linux-dvb] VP-1020a checksum and i2c errors

I am having problems getting my vp-1020a working under fedora.  Same
problem under ubuntu.
This is from the latest CVS.  I have as much debugging turned on as I can
stand.
Everything works fine under windows so I dont think it is a hardware
issue.  The linux drivers will sort of work if I code around the checksum
error. ns-scan will find channels an tune to them so I know something is
going on.
Any idea why I am getting checksum errors and having problems with the i2c
communications (I assume)
