Live Buffer Playback Skips

[Black Hole]

I'm still testing my second HDR, and was using it to buffer PickTV this evening - but delayed playback was jumping every few minutes by maybe 10-14 seconds, and yet when I skipped back the jumps did not repeat.

Initially I feared disk problems, but recordings play back with no problem, and live buffering on other channels (BBC1, BBC1 HD, Quest) shows nothing similar. I therefore conclude there is something about the specific PickTV data upsetting the HDR.

(Just for the record)

Does it still skip if you save ithe buffer as recording and then play it back?

Don't know, I will have to recreate the conditions under which the symptoms occurred (might not be easy) and try it.

I have noticed something that I believe is similar to what you describe. I have noticed that when buffering live video, the play back from the buffer appears to be at a slightly faster rate than the live video, so eventually you catch up to the live video, and then you get a little jump as it switches from the buffer to the live feed.

I don't think that is normal, I usually watch TV with a very small time delay (e.g. pause imediately followed by play) because this gets rid of 'Red Button' and 'Book Me', but if I watch the same channel for hours, the Humax still doesn't catch-up to real time

Definitely not the same. I can't see any reason the playback should empty the buffer faster than it is being filled, unless you skip the adverts of course!

Well, I had another look tonight and got the same symptoms. I then recorded the buffer and the recording playback did the same thing (skips which did not repeat on replay). I had a look at the signal strength and it's down to 10% (downstream of HDR1).

I think the signal strength is the key, but it produces an effect that I would not have anticipated - faulty data in a recording ought to play the same every time, right?

To confirm I will switch the aerial feeds and hopefully the symptoms will transfer to HDR1.

I can't do this experiment now because while I was reconfiguring a connector fell apart, and once repaired the signal strengths are up to 60%!
