scuwp: Micro-loss of signal is a known TiVo issue and I am sure there have been other threads on this. There are display output settings in the TiVo (somewhere under settings>video>display or similar off the top of my head) You need to ensure that the TiVo video output matches what the TV can handle (or the amp pass-through) from memory most on-line comments suggest that one of the "hybrid" settings works best. There is about 6 to choose from and try out.

Thanks for the suggestion, I have tried both fixed and Hybrid settings with the same result. 
The fixed 1080i setting it was on when it started doing this is the same one it has been on for over a year prior without any signal loss.  I definitely seems to be something that has developed.

Another forum suggested that it might be a HDCP handshake issue and I have taken the steps suggested in that thread to no avail. Something is definitely bugging the HDMI signal causing it to reconnect.

Could another device in my setup be intermittantly spiking the TV's media box causing the TV to re-establish the connection?  I can't recall whether this started before or after I got my Blu Ray player at the end of last year. I will disconnect that from the TV for a few days and see if that has any effect.

The TiVo has no interupted signal as I can skip back and play the few seconds I missed during the black out.

Alternatively I could buy a replacement at $360 from TCom and move this one to the bedroom and use the wireless adapter finally.

I have 2 TiVo's. Both connect directly to the TV via HDMI, one a Samsung Plasma, the other a Sony LCD. I have swapped bits and pieces around all over the place eliminating everything I can and have concluded that it is the TiVo itself, and only one of mine does it. Therefore IMO it is actually a 'fault' with the unit to do with the HDMI output.

I am not satified going back to component cables. Whats the point in having HD equipment if I do that.

At the moment I am being tollerant, although it is annoying. If it is still doing it near the end of the warranty period I may ask for a replacement. Other than a reset (unplug, leave for 6 hours, turn on again) the helpdesk were clueless, and it dosn't sound like much help can be had from Hybrid right now seeing as they are all but can't talk to them anyway.

I live in hope the new TiVo owners in AU can get there act together and fix things like this.

wallop: I'm pretty sure component is SD only.

That's my understanding too - that TiVo went along with the Freeview spec to allow HD output on only the HDMI digital connection. Component and other analogue outputs are SD only.

Also, the skip function is disabled as part of the Freeview spec. I'm sure though, that that decision would have been under the influence of the Network Broadcasters.

Hmm, might have found the culprit and some embarrassment. Embarassed
I completely didn't remember that my arial cable was going in and out of a DSE surge protector.  I rediscovered this fact when I was fiddling about in the spaghetti bolognaise of wires that lives behind my home theatre set up and saw it attached to the end of the surge protector.  I thought "hang on a minute" and removed the surge protector from the equation and screwed the arial straight into the TiVo. Undecided

So far it's two days with no signal loss, fingers crossed this was the cause. And fingers crossed I don't get a lightening strike.

How long before I consider it the root of the problem and give DSE some crap over having a dodgy SP which presumably spikes the arial socket somehow.Yell

I'm pretty sure skip and HD over component aren't disabled because of adherence to the Freeview spec - Tivo isn't Freeview accredited and that's why it doesn't have the full Freeview EPG. More likely it's because TVNZ is a major investor, has a vested interest in ads not being skipped etc, and has imposed this as a shareholder.

Just to update from my previous post...

After realizing that the component output on the TiVo is locked at 576i, I have switched back to HDMI. Setting the TiVo device to 'Fixed 1080i' seems to be the most stable for me.
