Ok, so I got the 421 the other day. I'm am pretty well versed in Meridian configuration but I can't get the G68 to switch it to the assign inputs and it's really annoying me. Despite the GUI showing me that I have stored the correct setup to have the G68 use H1 for HDDVD and H2 for my PS3, it keeps defaulting to H1 for PS3 and H4 for HDDVD. I have subsequently stored, tried, deleted, recreated the setup about six times now and no go it won't memorise the setup as per the GUI. Surely, it's shouldn't be that difficult to get the comms to work properly? I updated the system firmware first off the other day to make sure everything was up to date as well.
