My BV8-40 suffers from intermittent break-up of both sound and picture on all channels. I updated the software to 0.1.7.1.0.  but unfortunately no changes to the reception quality.  The aerial feed is providing 100% signal quality and strength from the local transmitter. Another more distant signal with a lower signal level is unwatchable on the BV8, yet I plugged in a GBP26 box to the same aerial feed and this handles all multiplex's from both transmitters with no interference at all!  

The new DVB-T/C software finally silenced a very intrusive fan but perhaps there's another bug in this version to annoy me? Any suggestions appreciated
