Hi, I have a 3 year old External USB2 DVD drive that is basically an IDE enclosure for any standard internal DVD drive/burner. I'm looking to replace the drive inside with a high quality one that supports DL burning on all types of DL disks as quickly and safely as possible. I have an iMac with a Pioneer K06A drive that isn't a year old yet. Sadly it doesn't seem to be reliable enough burning even standard DVDs, so I'm not risking more expensive DL media in there. I've been successfully using the external USB burner for about 6 months now. Sure, it's noisy and bulky, but it's quicker and more reliable than the useless drive Apple decided to bung in an otherwise terrific machine. All I need now is for a recommendation of a Mac compatible, OEM DVD drive that is tried and tested (and quiet, if possible). I was hoping to buy from the likes of Ebuyer.com or Misco as I'm in the UK and they've served me well in the past. Thanks in advance.
