Have you checked in the database that you are receiving that Mux from Mendip and not another transmitter? I am also in N Bristol and I can record from that Mux with no problems. The transmission parameters for that Mux are the same as 3 others with only the one with Sky News using qam_16 (according to my database). 

I had problems receiving transmissions from "up north" so I used the file created by running the linuxtv scan utility to control which frequencies were scanned. If you are using eit you will need to edit the networkid in the database to make eit work (quick insert of 5 values).

I am using 0.23-fixes but can't see why 0.21 wouldn't work as the Mux parameters are the same as the BBC Mux.

Let me know if you need more help
