Yet another with the problem, seems only to affect iPlayer on my BDP370.

ISP: Be usually connected at 7mb

Firmware: M03.R.695

iplayer thru laptop unaffected. Copper between BDP and Router.

Used to work fine a couple of months ago, now unusable.

I can guarantee that Zen do not run a proxy server or any other traffic shaping or filtering.

Let's just say I have insider knowledge and leave it at that...

I've had this problem and been contributing to this thread since the start of the new year.

With O2 8meg couldn't watch anything iPlayer on my BDPS370 (SD or HD) for more than ten or fifteen minutes before constant buffering would make the programme unwatchable. As with other posters iPlayer on PC was fine.

On Monday I had BT Infinity installed (40meg). Last night I was able to watch a whole one hour HD stream and a half hour SD stream on the S370 perfectly with no stalls or buffering.

Admittedly this was just one night and I may see the problem return, but when you read through this thread and see the majority of people with this problem seem to be on the O2/Be network it makes you think.

Maybe just the extra bandwidth from the Infinity product masks the problem although it's still there?

Is it possible some type of proxying or shaping O2 are doing is conflicting with something on the S370? Maybe something to do with LLU providers?

Will post back in the next few days if the problem re-surfaces with BT.

I don't think it's a bandwidth problem as, like a couple of other posters here, I have a sony Bravia KDL 37ex 503 internet TV which is connected to the same router as my S370.

The TV plays I-player perfectly but the S370 buffers every 10 mins.

I updated to .742 a few days ago and sat down last night to watch "The Chinese are coming" pt 1 in HD.

Flawless.

Of course this is a one off, so need to see a lot more first. I do note I've seen no issues with the current internet connection for iplayer from PCs or Samsung -- ever (only had it a month). The connections is approx 31 Mbps down, 8 Mbps up measured data speeds (inc. peak)

So far too early to tell - I had issues before..

I'll just add to the list...

My BDP-S370 is connected by wire to Virgin 10Mb/s cable broadband.

I get buffering problems which can start any time after about 10 mins of playback.

Firmware is the latest firmware from the auto update feature.

Seems to be exactly the same issue that everyone else is reporting.

The problem started around Christmas - before that all was fine.

Sony - you're hiding from this one.  Please talk to us!

I did the firmware upgrade on the 16th Feb to my BDP-S370. (By creating a disc, rather than a network upgrade). And so far I haven't had any more buffering issues on iPlayer (Both SD & HD).

Same problem here.  BBC iplayer does not work anymore.

1. Decent broadband connection.

2. Ethernet connection to BDP-S570

3. Latest firmware

4. It used to work perfectly and now it doesn't.  Iplayer plays fine for about 5 minutes and then stalls and buffers every 30 seconds or so.

5. Works perfectly on all my PC's, so it's not the broadband or my network, is it!

I am 100% convinced this is down to the BBC iplayer changes made a few weeks ago.  It is the BBC's fault, I am sure.  But we need Sony to talk to the Beeb so the 2 companies can fix it between them.

As it stands, I have a Sony device that is unfit for the purpose for which it was sold.  It is 3 months old, but nevertheless, I will be returning it for a full refund unless this gets fixed.  I already own a BDP-S350 I was quite happy with.

I only bought the 570 for the iplayer facility, and as it stands, IT DOES NOT WORK.  Sony, please can you do something?
