I just have some preferred movies & concerts with some bookmarks set so I can get to the sweet spots quicker. A bunch of preferred CDs as well.
The only true demo disks I have would be a BR music sampler & another DVD sampler from AIX records as recommended a few times by Ian. He was not wrong! The 5.1 sound staging effect in the BR is unparalleled in anything musical I have so far.
AIX HD-Audio Sampler IV Also, it has just about every genre on the disk so there is something there for whatever your target audience is so it's an easy pull for demos.
