I think I've now sussed out on my Humax HDR so that I can adjust the times (up to 4 minutes) for the skip forwards (>>|) and skip backwards (|<<) buttons, but what about the > and < buttons on the chrome ring around the around the OK button?

How long are their skips (forwards and backwards) set for, and are they adjustable?

No they aren't adjustable they just skip through the recording for the duration of the button press.

They are not adjustable they move the playback position. The longer you press the further the playback point moves

I didn't even know you could do that!

Aaah, very interesting! I'd only ever dabbed at the chrome ring > and < buttons (because of my previous experience with a Wharfedale PVR, which gave 30s forward and 15s back, useful for skipping adverts!), and the time leap seemed to make no sense. Now I know why!

So what, then, is different with the chrome ring > and < buttons and the >> and << buttons (those beneath the play button)?

Questions, questions!

Those are the forward and reverse playback speeds.. it toggles through x2, x4, x16, x32, and x64 and then back to x1 playback.

The two left hand ones are fast forward and reverse push them several times to speed up fast forward/reverse playback. The right two in playback are the programmed skip keys. By default +2min -15 sec. (great for skipping ads - hit forward skip till you see the ads then back up in 15 sec increments)

I find this handy when the box is left on to fill the buffer on the channel I want to view at a later time. Just press and hold the < button and it whizzes to the start of the buffer in seconds.

Yes, I've sussed out how these buttons work, but what I'm asking (not very clearly, obviously!) is by how much the chrome ring > and < buttons round the OK button skip forwards and backwards?

We've already answered that in posts #2 and #3.

Played around with the buttons I'm on about during the live footie last night, so could see clearly what one press of them does: > goes forward about 20s., and < goes back about 40s.

(I understood what was said in posts 2 & 3, and have now used that information to good effect [a very fast way of skipping through a programme, for example]. I was just curious about what one quick press would do... )

In LIVE..Surely
One quick press of > does NOWT!

Stan

It does if you have first pressed <

OK, OK, I should have written '< goes back about 40s and then > goes forward about 20s'!!!

This is where the handbook is crap! There's no explanation of that listed.

I would have thought that the movements of the < and > buttons...
moved the Playback ZERO point in a symmetrical fashion..
I see no design requirement/advantage in departing from a Balanced Control situation for those buttons..
I certainly hope that henceforward..
no-one takes the Asymmetry for granted,,
let alone the values ascribed by you without further checks.

That's because there's no circular arrows on a PC keyboard and no keys on a hdr remote with < or >. .

The keys on the remote have standard transport function symbols.

I have to say, if this is meant to be poetry, it doesn't scan...
(Ellipsis intentional!)

As i suspected
the Arrow buttons around the Silver Bezel
perform entirely Symmetrical functional movements..
I used an hours recording of a T&D tour in SD and found that..
Horizontal jabs repeated.. give approximately 15 Seconds movement..either way.
AND
Vertical jabs repeated..give approximately 7 to 8 Minutes of movement..either way.
I was a little surprised when the same figures emerged when analysis was done on a 1 Hour 'Life' prog in HD..

I know not of many 'Scouser' Poets..Substance not Style has been my watchword..

Her Indoors will be most upset that you've not heard of the Liverpool Poets, of whom she's very fond.

I do not meet many 'Scouserphiles' down here..
so.."Which Foot does she kick with?

The up and down buttons (on the circle) also move forward and backwards by 12.5% of the length of the programme

For completeness you can also punch in an absolute time by using the number buttons. eg 0037 goes straight to 37 mins and there's also the bookmark facility

Isn't that just great? 12.5% of 1 hour is exactly 7.5 minutes. Well done, chaps!

Not that I wish to argue with m'learned (Scouse) friend, but I'm sure I found a difference between the > and the < buttons on my Humax HDR. This, to me, makes perfect sense: as I mentioned in my OP, the Wharfedale PVR I was using had asymmetric timings, and for good reason: 30 secs forward and 15 secs back was great for getting close to the end of commercial breaks. Symmmetric timings would just have one shunting back and forth to and and from the same points: not very useful at all!

Well I did not know that one.
Any more?
