As regards all the helpful hints to improve the speed, let's not get too carried away.
At long last I had my two Tivos replaced yesterday. The bad news, with nothing on the boxes, no scheduled recordings, no recorded programmes, they were not as fast as I would have expected.
I then copied my schedule over to one box and recorded a couple of programmes last night. I had a whole 3% used. And I waited for the menu to appear and I had a wait while it loaded, slowly, one of my handful of recordings.
This was on a new, virtually empty, box. Very impressive.
So to the suggestion of an upgrade to resolve the situation. I would not hold my breath. After last year's update fiasco when they managed to lose Dolby Digital off the Samsung boxes, it took about fifteen months to resolve this with the recent upgrade.
And, as for the current issue? Remember that the code on the current Tivo is the same as that on the more powerful V6 (that is what I was told by the CEO's office), so no wonder the Tivo is struggling.
However, if they want to keep the codesets in line to reduce maintenance costs, very likely, then any changes will have to be made to both the current Tivo and the V6.
And they will then have to test both models and their testing procedures seem to be pretty useless, otherwise they would never have got as far as releasing such poor upgrades.
Nice to be able to post again, after their mistake (removed by the Censorship team). ¡No Pasarán!
