A few weeks ago, the on demand services on my HDR-1100S started continually buffering, every 2 or 3 minutes for maybe 5 to 10 seconds – they used to work fine. On demand is currently unusable 
This applies to all available on demand services – BBC iPlayer, UKTV Play, ITV Hub.
The HDR-1100S is connected by ethernet cable to my modem/router and I get an internet download speed of 23 Mbps.
On demand services work without any problems on my desktop PC.
I have reset the HDR-1100S to factory defaults.
I have turned off and removed the power cable from the HDR-1100S – several times.
The buffering problem does not depend on day or time or programme.
I have requested a software update for the HDR-1100S – there isn’t one available, I’m told.
Any suggestions as to what is causing the problem?
Or should I just bin it and get another …?
