They are drivers for different cards. budget-ci is the driver for Technotrend
C1500 among others. budget-av is used for e.g. KNC1.

This is because of a bug in the driver. It might work if you upgrade the driver
to the latest version, which has a fix for the QAM 256 problem. However, if your
card has two antenna connectors, it might not work anyway because of a different
problem (which I have too).
