Picture break-up after using Pause
grahamdeepwell
26-01-2009
Foxsat HDR - when viewing a program in HD that I have previously paused (is it called chase-play?), I get picture freeze and break-up for a couple of seconds. This happens about every 10 minutes. If I fast forward to 'live', it doesn't happen.

This seems to occur when I am recording another channel. Is my box faulty?

I dont think it's faulty. I think it's a " chasing playback" bug.

I reported it in the bugs section....

I was recording heroes on BBC HD and also watching it. I then paused the recording for a few minutes and then started watching it again. When the program finished at 10:45 it also stopped the live pause and dropped out to the live channel"


....... When I restarted watching the paused recording I "rewound" the picture a few minutes from where I had paused it. When it reached the pause place I suffered picture breakup/pixelation for a split second. I managed to recreate this probelem every time I did the same thing. When it reached the pause point it "faultered". It was still recording whilst I was doing all this and then it finally dropped out completey what I was watching when the original recording end time was reached, as pointed out above.

Thanks. I'll have to live with it anyway, Comet will swap it out for me but they can't get stock. Hope the shortage is not caused by excessive returns.

Will bugs like this be cured by updates, eventually?

I'm assuming it's a bug and that me and you have not both got faulty products!!

Anyone else out there got a similar issue? It's easy to reproduce by pausing an ongoing recording by chasing playback.

To be exact, there is a scheduled recording taking place and I'm watching another channel. If I pause the program I am watching, then start it playing again, that's when I get the picture problem.

If there is no separate recording taking place, I do not get the problem.

Any takers out there with the same issue?

I've trawled the Bugs thread briefly and cant find any other comments. If I've missed it, apologies, but I'm wondering now if this is a bug or a fault.

Just tried to reproduce this, set ITV1 to record, during this recording changed to bbc 1 paused it several times and resumed playback. No problems at all. Try a factory reset and if problem still there it could be a problem with your unit

Try recording BBC HD.

Not quite those symptoms, but I have had two different types of video problems: last weeks Hustle (BBC HD Thursday) where there were quite a few picture break-ups - I put it down to a broadcast problem but maybe it wasn't - it was recording other programmes at the time and the disk is near full.

I've also had a couple of occassions when I've paused an ITV HD programme, un-paused and the video seems to be playing frames back in the wrong order (no pixellation or break-up, but it looks like it's playing frames 2 3 4 1 5 or something). Stopping the playback and re-starting it fixed it - so it wasn't a problem with the recording itself.

Recorded BBC HD, paused ITV 1 replay no problem

Recorded BBC HD and BBC 1 CI (same transponder), paused ITV 1 replay no problem

Could it be HDD space related. Mine has a 1Tb drive 16% full with all HD recordings

Everytime I have had the problem I was recording BBC HD. Started watching it from the beginning whilst the recording was still in progress. Paused it for a while... (phone rang)... rewound it a few minutes.....restarted it a couple of minutes later and when it got to the pause point I suffered pixelation break up at exactly the pause point. Repeating the excercise replicated the problem at every pause point. It was as if the buffer was struggling to handle recording and pausing the same programme at the same time.

No other recordings were taking place and the disc is only 25% full.

Edited... forgot to put in the rewound back from the paused point bit.

Before I try and reproduce this were you using chasing playback (replaying the actual recording) or simply rewinding the buffer (tsr) ?. I know for a fact that I have no problem with the former but have not tried using tsr with a programme thats's already recording as it's much easier to just use chasing playback. There is a known bug/limitation in using tsr on a channel that you are not already recording and subsequently decide to record (you can't add the buffered material to the beginning of the recording)

Tried every combination while recording BBC HD.

Using pause rewind replay using tsr buffer and
using playback of recording file from media list.

No picture break up at all.

Hi Graham,

Sorry... work got in the way.... I was chasing playback of an ongoing recording. i.e. started watching it before it had finished. Paused it ... rewound a few minutes and then restarted. So effectively using the buffer whilst in chasing playback mode... if that makes sense.

Hi, it makes sense, but as you can see it's not repeatable on mine. So it looks as if there's two possiblities

Hardware fault eg Faulty HDD
Software fault - eg corrupted firmware

Factory reset should eliminate latter option, other than that run out of ideas.

Really need some other forums members to test this to see if it's isolated to your stb or affects others. If others are similary affected there might be some differences in setup or usage that it might be possible to identify

Thanks Graham... I'll try to recreate the problem this evening and if it happens I'll try a factory reset.

Other than this, which only amounts to a "minor stutter" when the pause point is reached, I've had no other recording or playback issues.

Tried to replicate this last night and didnt get an issue.

Hopefully the problem has now gone.

Update: Last night I was watching Lark Rise on HD, not recording another channel. I paused to answer the phone, then resumed on chase-play.

Still on chase-play, Charles Darwin started. After about 30 minutes of that, I began to see brief freeze and pixellation occur, roughly 10 minutes apart.

So it seems to occur after an hour of chase-play.

Interesting... I couldn't replicate the problem last night but I was only chasing playback by a few minutes behind recording.

Managed to get break up twice last night whilst chasing playback of an ongoing recording of WDYTYA on BBC HD. I hadn't rewound this time, just a pause and a restart.

It wasn't snowing at the time either!

I've seen a few of these too, typically when I'm recording something and watching something else. Minor picture & sound breakup for say 1 second then it recovers.

Sorry, I've been distracted the last few weeks. Comet has exchanged my Foxsat HDR, no problems with the new unit.

Anyone having similar problems should go for an exchange.

Thanks for that. I haven't had the problem recently. Its not happened when I've paused the live buffer but not tried to chase playback of a recording for a while which seemed to be the main cause.
