I would echo this review. The menus look lovely with the images for each show etc but it takes way too many clicks to get through to anything - further compounded by the delays. I can't say I was expecting the picture to change,given the resolution is the same - are you confident it has?
My experience is that there is a clear degradation in sound. I am feeding the sound through the HDMI and the receiver has to be set on WAY higher volumes than the iQ2 - and the vocals often seem soft relative to the ambient music and sound. It is not consistent, so I suspect that some audio formats are not being handled correctly within the box.
_further to this I have had shows on series recording record 54 minutes instead of a full hour - and miss the end! That is just crazy! Fixed by adding 30 minutes but seems a complete waste when most shows outside of sport don't run over.
_I have had real issues with series recording. Haven't been able to play or delete shows. Generally fixed with a reset but it completely missed the Brumbies QF this weekend - a real pain!
_Often getting messages on recorded shows that the box has lost power - but usually hasn't lost anything
_I have started the box to a blue screen many times in the few weeks I have had it. Fixed with a reset (holding power button for 5 seconds), but still a pain
I was keen to get the extra capacity (HDD 3x larger) but I have to say I would advise against anyone upgrading just yet. Hopefully they fix (and not abandon) this model....
Picture quality - yep, definitely better, all the family noticed it, someone posted that the IQ3 has a better video scaler.
Audio quality - maybe slightly softer volume, but definitely better quality, plus I could never get a decent / solid HDCP HDMI handshake with the IQ2 so I had to use a toslink connection to the processor. With the IQ3 I have rock solid handshake over HDMI, never had one single problem.
We've had no problems with series links and the occasional (rare) "lost power" recording notification has diminished to zero over the last couple of weeks (touch wood haven't had one for the whole month of June).
No blue screens on start up, but locking and rebooting (as per previous post) is not unusual, even the boss is getting quite good at it.
FTA TV channels quite often go overtime / start late so I've added 30 minutes to the record times for all FTA channels. As a result I haven't missed any program beginnings or endings, so far anyway.
I don't know whether cable IQ3 is a bit more "reliable" than the satellite version, but I don't see the same issues as others have reported.
