Green Lantern:Ext. Cut

[Trekofile]

Just got my new BD copy. While trying to engage the Pic in a pic feature entitled: Max. Movie Mode GL's Light, I can get the pic in a pic window on lower left corner playing video, but ZERO volume! This is prevalent first several offerings, whereas some windows are expanded to full screen interrupting feature film and plays fine. But many remain smaller windows playing w/o sound. Thankfully I think these are available to view as featurettes individually else where on the disc menu, but still aggravating when the PIP non-video, rather just graphics w/ texts play fine, one cannot watch both and enjoy, as the volume is not available. last update for my BD player was 5/2011. Now discontinued by Sharp(BD-HP210U). Anyone have any tips as to how to gain sound back on pic in pic video in movie mode? Thanks!
