Hello again, I’ll use the same thread because it follows on…
I’ve read the advice and links re AR as opposed to padded recording and I decided to try the AR way of doing things. Reset my padding to OFF and let it run…
Very impressed on the whole, but I have had 2 recordings which have missed the last 2 or 3 mins (hard to tell but they were nearly finished). I think the first was on BBC2 and the second certainly was, I’m pretty sure they were not delayed but I deleted too quickly to go back and check (the second was Whale Rider at midday Saturday).
I’m about to return to the old method of padded recording but that would be silly if I’ve missed something because the concept of AR looks so good.
Is this a common thing or is it perhaps a problem with the nut on the handle?

When I first had mine, I set it up with padding, but that caused all sorts of problems – so I decided to remove the padding, and it has always worked perfectly for me without. I can’t comment on why you missed bits of programmes but, as I say, mine have been ok.
With padding, you get conflicts if you try to record two back-to-back programmes on the same channel because the bits of padding overlap – and it says it can’t do it. I seem to recall that what it actually does is to carry on recording the first programme through the padding period, and then starts the second programme late. It has, of course, recorded both programmes – but the start of the second one is in the wrong file!
So my conclusion is that the disavantages of padding outweigh the advantages.

As a newbie to the Humax (though used PVR a lot before) what exactly is a mux (multiplex) and why can you view from the same mux but not outside of it (when recording two other channels). I know a bit about channels etc but I can’t get my head round this one !
Oh and as an aside, looking at the link to the mux channels I notice that the quite interesting Movies for Men channels (no these are adventure films, not what you might think !) that we can recieve seem to be only from the Winterhill transmitter, does this mean no one else can get them ?

A mux is a single broadcast channel which is a mix of a number of TV and radio stations. Each tuner is able to decode one MUX at any one time. So as the PVR has two tuners it can decode two MUXes and allow you to record or view any TV or radio stations on those two MUXes but not from any of the other MUXes being broadcast. There are six MUXes being used altogether(*), one of which is currently dedicated to the HD stations.
(*) From main transmitters. Relay transmitters only broadcast three MUXes.

A multiplex is just a combination of channels transmitted on one frequency (similar to a cinema mutiplex having several screens in one building). Old analogue channels equated to just one frequency whereas using a process called QAM (I’m not going to attempt to explain that one 😉 ) several bitstreams, either TV, radio or both are combined before transmission on each MUX and decoded by the PVR or IDTV into LCNs (logical channel numbers)
Take a look at the FAQ item Which Channels Can I Watch While Recording 2 Others (link) for the second part of your query.

Are you sure this is the case WT? Over on the Hummy.TV forum (am I allowed to mention that here?
) I found this in the Wiki:“Note :- The Humax can’t record the same channel at the same time twice, Even if there is a free tuner, So padding between consecutive programs on the same channel will be turned off and EPG times will be used.”
That seems to suggest that padding might be the safer option.
I can confirm that at least for the HD FOX T2. If you have a tuner committed to two recordings in succession it will drop the intermediate padding even if not on the same channel (this is different to the Foxsat). Change from one recording to the next will take place at the scheduled time. AR will delay an overunning recording till it’s complete before starting the next (preserving the end at the expense of some loss of the beginning of the second). Using autopadding any overun of the first will lose the end of the first recording.
So far recording only HD channels on the HD FOX T2 AR has performed flawlessly.

That doesn’t quite accord with my experience. I don’t think I’ve still got the evidence, because it was several months ago, but I distinctly remember finding the first 5 minutes of Prog2 tagged onto the end of Prog1 when I told it to record two consecutive programmes on the same channel when using padding. So the start of Prog2 was in Prog1’s padding. It had, of course, dropped the padding at the start of Prog2 – and I don’t think that I had actually lost anything because File2 carried on from where File1 had stopped.

These are the observations I made from a series of tests. I don’t normally use auto padding. It’s very easy to set up some test recordings and see what happens. Just set up a long recording to cover more than the period of the test. Now set up two recordings on different mux and and a different mux from recording one. You will only lose content if the first of the consecutive recordings overuns the time it’s scheduled to finish and it’s not on the same channel as the follow up recording. If the two recordings are on the same channel of course whats missing from on will be on the other.
