I have a message from Panasonic that reads ;

'Thank you for your patience in relation to the upgrade for iplayer on .

The provision of an update has always been subject to extensive testing to ensure the integrity of the product. During testing of the software two bugs have been identified, one of which is considered to be critical, requiring further work by our research and development team. As a result the release schedule has been revised.

I can confirm that a tentative release date for the update has been set:
2009 models (DMR-BS850/DMR-BS750, DMR-XS350EB)

14/02/2011 - available via Global website, to enable customers to download onto CD and upgrade.
14/02/2011 - available via Network download and an Over Air Download via satellite.

We appreciate the frustration this delay may cause and of course offer our sincere apologies. However the reliability, quality and overall functionality of the recorder must remain a priority.'

But don't hold your breath!

These are the satelite versions, I wonder if they will set up the same facility for the freeview versions. I hope so and soon.

Nothing happening here DMR-XS350EB

I thought Panasonic had pulled this update due to bugs?

Just updated my XS350 via network. All working fine,less than 5 minutes all done.
Long time coming but hopefully no bugs!
