   No, dual _layer_, not dual _sided_.   
      
   I've just had a look through my DVDs (probably for the first time in   
   years!), and I don't _think_ I've got any double-layer, but I'm not   
   sure; I assume they'd look a slightly different colour? I think the   
   longest is 111 minutes, and I'm not sure what the limit is for DVD5   
   (single layer). I do have something 199 minutes, but that's on two discs   
   (and the box explicitly says they're DVD5); that's a TV series   
   (THHGTTG), so no problem it being on two.   
      
   I'm pretty sure there was never a double-_sided_ (DVD - I know there   
   _were_ for floppies) drive; you just had to turn the disc over!
