SONY HX800 wont convert 3D SBS from YouTube

My Sony HX800 plays 3D videos from Blue-Ray, PC and 3D-compatible PVR but it won't recognise sbs videos when connected directly to the internet. It looks like a design fault, but does anyone have a suggestion to get around this?
Would be much appreciated.

 

A summary of three ways around this problem. (On all 2010 Sony 3D TVs.)

1. Connect a PC with a 3D-compatible dual-output graphics card (eg Nvidia) and an HDMI 1.4 cable. (This solves YouTube and local SBS files.)
2. Connect a 3D-compatible PVR (all of the current STRONG range are OK and Beyonwiz), which allows SBS videos to work from an attached USB or hard drive. (The high end of the STRONG PVRs also has its own internet connection.)
3. Connect a 3D Blue Ray player with USB and internet connection. (I have a Sony BDP-S470.) To connect to YouTube, apart from the channels in the Sony menu, you may have to have your own channel, as the Sony asks for a login name and password.
No problem of course with Blue Ray 3D disks or standard DVDs created with a 3D SBS video file (AVCHD).

Later Sony models (from 2011) don't have this 3D menu problem.
