I want to know the answer to the following question:
How many 5.1 surround sound options exist in LaserDiscs?
All the background I'm provided with is that "Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser.". Is that enough to answer the question?
Answer: yes
