Any titles with Dolby Digital Plus?

[GregBe]

Hi all, I could use your help. I just bought a Roku 2 XDS to stream Netflix, and it sends out a Dolby Digital Plus signal. My receiver (Pioneer 94 TXH) decodes DD+, but unfortunately, I have never had an occasion to use DD+, but now I do. I am getting no sound at all when I choose DD+ through the Roku. I have tried every setting on my receiver to no avail. Before I return it, I figure if I can play DD+ through some other source, I would know if it was my receiver or the Roku. Someone said that some Blu-ray commentaries are in DD+. Do any of you know of any titles (hopefully in my collection) that have DD+ that I could try out. I have a Blockbuster down the street, so I could always rent one to troubleshoot (hopefully a catalogue title, so I could get it for $.99. )

Thanks!
