Talk:List of film sound systems

Dolby analog formats
The article currently says: However, Dolby SR (spectral recording) does not necessaryly equal surround, and there is an actual article for Dolby Surround. Can someone more knowledgeable shed some light on this? Are the numbers' total correct? Are they correctly divided between the two? Should another line be added to distinguish between Dolby, SR and Surround? Does a list of Dolby films exist outside of IMDb? -- Katana (talk) 13:33, 4 August 2013 (UTC)
