Hello,
Can someone explain the difference between a 2.0 track and a 5.1 track on a DVD?
And does it change anything in terms of sound, image, or anything else?
Thank you

initially, all sound was mono, that is, 1.0 (for a single channel only). then it modernized and we could have sound in 2.0 for stereo (left and right channels). later, 4.0 appeared, equivalent to 2.0 x2 to provide a bit of depth and thus better sound distribution. then the first dolbies arrived like prologic, dolby SR, dolby SRS... which are specializations of stereo sound and simulate multichannel sound with a left front, right front, center, and 2 mono surround channels. then it improved further, dolby prologic 2 came along and replaced the specialized mono surround with 2 distinct channels. then the first dolby digital 5.1 appeared with digital sound specifically made in DD 5.1 to achieve perfectly multichannel sound. but then, some employees at dolby had an idea to compress dolby less to make it better. but that didn’t please dolby, and they basically thanked them. later they created the DTS logo in France, which is based on a similar idea to dolby but with a different encoding, lower compression providing better overall sound than the best dolby in the same range (I’m not talking about HD sound from blurays, for example). thus, competition was born and those who love good sound would prefer dts for its more dynamic and reactive quality.
dts, like dolby, is often associated with either 2.0 or 5.1 but there are many movies and music DVDs with dolby digital surround sound that provide a center channel at the back, like in Harry Potter or Star Wars, or a dts es matrix or dts es discrete that also offer sound with a center channel at the back as found in 007 Die Another Day, for example.
for high definition sounds, in addition to the sounds mentioned earlier, there are dolby high definition sounds (or dolby digital plus), dolby true hd, dts high definition, and dts master audio. the high definition/plus provides better sound than the "classic" dolby or dts, and true hd or master audio offers studio quality without compression with significantly better sound from dts (which is why we find it more and more). among the indicated hd sounds, there can be ranges from 1.0 to 7.1, the majority unfortunately being 5.1. otherwise, there’s also pcm which is also uncompressed and sometimes better than DTS MA but sometimes not; it also depends on the ear.
in short, one should not mix 5.1 with dts or dolby or others. 5.1 indicates the number of speakers (3 in the front, 2 in the back, and the .1 corresponds to the subwoofer). dolby or DTS indicates the type of audio encoding.
Best regards
