at face value, to some it looks like going backwards but....
I can attest to the fact that with a few DVD's I own, namely the MI-5 BBC series and several others, that using the 2 ch track and adding PLIIx does
produce far superior surround sound than the encoded 5.1 track
I found this true with the original ADV Farscape DVD's, too.
On the MI-5 discs, there was hardly any sound in the surrounds, which really surprised me since the HD version of the show on TV using basic Dolby Digital had more subwoofer activity and a lot more discrete & enveloping soundfield than any of the DVD's.
I attributed that to poorly engineered 5.1 tracks on the discs. So I tried adding PLIIx to the 2 channel tracks and it sounded far
So before criticizing your practice as going backwards or inferior to a 5.1 track, I think it all depends on how the recording engineer decided to use the surrounds when creating the 5.1 track.
For Blu-ray or other HD sources, though, I have not done it your way, nor probably will I
I do add PLIIx matrixing but always start with the hi-rez 5.1 audio track.
Call it being lazy or sloppy on the part of the recording engineer, but I do think some movies & TV shows have surrounds added as an afterthought with no attention to how they may be used to enhance the experience. For those, I see nothing "wrong" with your method at all
