Hi Diesel,
I bought a second DVX 555U around June 2009 and it had the latest firmware at that time on it. I use it instead of the old one (bought in 2007 or 2008) as it has twice the signal strength, not sure why this is.
I updated the firmware (around Oct 09) on my old system to see if it made a difference in the signal strength, it didn't, but it still tuned in channels and worked like it did before the upgrade.
Is this a newer release of the firmware? Where did you get it from? Can you contact the people that posted this firmware?
Going by the posts on it appears to be newer firmware, maybe not recommended for the Australian model.
I saw a few still on sale before Christmas for $49 at Homeart.
All other avenues for support are pretty much closed unless you find an equivalent re-branded model overseas that has experienced this issue.
Have you tried to contact jok11n? He might have some advice on firmware.
Regards,
malcolmturnbull.
