I have an IdeaPad Y570 Laptop - 08626JU  and the bundled PowerDVD 10 software does not seem to work - it failed to play blu-ray discs due to the software repeatedly failing to update. 

When I try to install the update it gives an error about not being able to find an internet connection, even though I'm connected.

There may be an issue with the auto update feature on some versions of the software.  Later versions are likely to become available over time.  To resolve, try the following:

Launch the PowerDVD application, then click on the hammer and screwdriver icon in the bottom row of icons.

From the resulting menu, select the patch and update tabs or, for simply download version 10 from this link
