Selected chapters on the Rolling Stones "Four Flicks" DVD set claim to utilize a special multiangle feature utilizing "MX Multiangle" technology. The "Select-A-Stone" feature is supposed to be available, for example, on Disc 2's "Honky Tonk Women." I have played this track in both a Toshiba SD-4700 and a Panasonic DMR-HS2, but in neither case have I succeeded in displaying alternate angles. The disc does not respond to the Angle button, or to arrow buttons, which the MX multiangle technology supposedly utilizes. Has anyone else who owns this set been able to get this feature to work? Am I overlooking something obvious? Thanks!
