Strange sound error on empire strikes back

last night whilst watching empire strikes back, towards the end, there was a loss of sound but only the dialogue, all the other sound effects and music were there, just no actually voices. any ideas how that can happen

One of the sound channels were off I guess. It happens when I play certain DVDs on my faulty player.

A messed up downmix from the 5.1 sound track. In fact did the ITV HD screening have 5.1 sound ?

There seemed to be a few new shots in that version of The Empire Strikes Back. I got the new DVD release in 2004 which had updates, this seemed to have more.

Does anybody know if there is a never version on DVD with more effects than the one released in 2004?

Kind of related, but kind of not, I've noticed in a few shows in the last couple of weeks the sound of the gallery leaking into the main programme, most recently with The X Factor last night.

thanks for that, would have thought all the audio would be on one track, not seperate

there are new scenes, the wompa eating the tauntaun being the main one

There's a full list of changes here, but it looks like the last biggest changes were in the 2004 DVDs where they changed some of the cast to match the prequels - Ian McDiarmid as the Emperor and Temuera Morrison as Boba Fett.

It wouldn't be possible -- or at least practical -- to dub movies into other languages if that were the case (which would, in my not-so-humble opinion, be a good thing, but that's an argument for another day).
