I don't own this set (so please don't nail me on this), but I saw that for the Season 1&2 discs English subtitles are listed as a feature. This boxset is also available e.g. on play.com and they claim in the product description that the set has English subtitles.
Hi Stefan, sorry to gatecrash this thread, but as you have the box set I wondered if you could confirm if you have the option of turning off the laughter track on the first two series? I've read various posts on forums saying suggesting it was possible with the original dvds of series one and two. I don't know if you'll see this message, but hopefully you will :) Thanks.
