Well I ordered the newest Samsung drive because I had one before and it was purring like a quiet kitten. I also tried changing the firmware to NEC from Sony, but its no different, so that was nothing gained. Its annoying as its running all the way, all the time when watching any Music dvd or any dvd, its fan is very inefficient.

Sorry to burst your bubble, I don't think its right to say the vacuum cleaner sound makes it sound powerful. I have owned and built a number of Computers with drives that perform quieter and better, so Thats just something to say to keep one content.
Its 33.00 so who needs a dvd rom serviced? Its simple enough and cheap enough to replace.
There isn't anything different with the sizing or connections with Pioneer so Im sure that the Samsung should work. My only worry is prying off the front bezel, I hope it will come off nicely and be able to put it on if i need to return. The pioneer Is out at newegg.
