What's the deal with LPCM 5.1? Does it simply require too much bandwidth/size compared to DTS-HD MA and Dolby TrueHD because its uncompressed?
This. Way too much bandwidth. And if we count the three original 77 mixes and the 85 and 92 home video remixes plus a number of foreign language tracks... It adds up.
With lossless compression you get a perfect copy of the master track in a smaller file size.
