Improvements noted so far is that the new Audio Bypass mode introduced with 1.04 evaluation is still there. This means that you'll get great AC3 Dolby 5.1 on channels that broadcast this (sadly only TV3 at the moment. Please email/call TVNZ and tell them we want AC3 back on TV1!) and it autoswitches to PCM when this is the only option available. No problems with audio over HDMI now from the brief tests I've done here, and I don't currently have a proper AV receiver capable of decoding AC3 over HDMI. Also, any sluggish 'remote" problems should be fixed. Cannot say whether random audio dropouts have been resolved yet. In the short time I've tested it, I haven't noticed any.
I still have stock of the ET Receivers so feel free to PM/email me for a very good deal. I have one of the new Vantage Receivers here on evaluation, that can record to a USB HDD. I believe the ET produces a picture easily as good as the Vantage, at half the price. These are really great value.
