When the "av7110_send_fw_cmd error" occurs, it seems to happen when all the
Pids are set to "0" in my the channels.conf in VDR and I change channels
fairly fast.  This means that the firmware is scanning the stream for Pids
at the time.  It appears that if you switch the channels too fast before the
firmware can finish gettings the Pids, then the "av7110_send_fw_cmd error"
occurs.  I have always had hw_sections = 0.  One other variable that I did
notice is "static int pids_off;" in av7110.c.  I have patched the code to
make sure that variable gets initialized by changing it to "static int
pids_off = 0;".
