Jerky picture

I`ve just tried to watch `Sherlock` on BBCi player and the picture is quite jerky and out of sync. How can I rectify please? tia

Unless you've got quite an old computer (with limited processing power) or there's a really 'heavy duty' program already running on your PC, the problem won't be related to the way in which your PC handles the data which is streamed to it.

That leaves only one other possibility, which is that your broadband connection isn't really up to the job. Run a ping test here. (It's not difficult; you just click a button):

You're looking for a grade 'A' or 'B' result, which is what you really require from your phone line in order to get reliable video streaming. (Click on 'Learn more about grades', from the results page, for a more detailed explanation).

The run a speed test here:
http://www.speedtest.net/
iPlayer can theoretically be used at a speed of 0.5Mbps but, for reliability, I'd hope to see a speed of at least 2Mbps shown as the test result there.

If the figures don't seem good enough, ask your ISP why you're getting lousy results.

In the meantime, clicking the link at the bottom of the iPlayer page which says 'Use lower bandwidth version' will probably solve your problem, but with a slight loss of quality in the image.

Cheers Chris, I`m off to sleep now, attend to it in the morn, I`ve had a busy day and the old grey matter etc,etc.

You can also put your phone number (or postcode) in to the BT speed estimation page and it will give you an indication of what sort of speeds your line is likely to be capable of.

If it is hugely different to the results you are getting on the speed test page Chris linked to then that is an indication you may have a problem.
