I've looked into buying the BR but I keep reading about a 'glitch' where it freezes or something, in the middle of one of the songs. Does it do that?
I did a google and came up with this:
Led Zeppelin: The Song Remains the Same (both original release and re-release)
* 7-second TrueHD soundtrack dropout at 1:40:45, confirmed encoding error that affects all players. Lossless HD DVD version and lossy soundtracks on both versions are not affected.
! Warner has done a "silent release" of a corrected Blu-ray Disc. The files on the correctly authored disc are dated March 2008.
I played the blu-ray about a minute before and after that time stamp (beginning of drum solo in Moby Dick)and no issue at all. I bought my copy sometime in 2009. Source: http://forums.dvdfile.com/high-definition-software/65577-blu-ray-glitches.html
