I recognize the type number: it's probably from a company that is called "BTC" and it's a OEM drive (supplied with the computer when you bought it). Well, I'm sorry to say BTC is not known for quality products that last eons. So that may lend credence to reason number 4. Hope you got your warranty still.
You might try flashing the firmware if you know how to do it. This site has the correct flash file:
http://etna.rpc1.org/mt/ (middle of page). Be careful though, you have to know what you're doing.
Those strange sounds are probably endless retries of the drive to find the "beginning" of the disc. That may point to a bad burn.
So I would try this in succesion:
1 Try the DL DVD in another computer: if it works it points to the drive as culprit OR the format is not supported in your drive
2 Try other non-DL DVD's in your drive: if they don't work --> drive has more problems than you knew (helpful, isn't?
) Beware of the format issue
3 Try an official DL DVD in it (for example a rented movie) --> if 2 works but this fails the drive may not be compatible with DL DVD
4 Try another self-burn DL DVD in it if possible
5 Update the firmware (usually voids warranty!) and try above steps from 2
6 Toss the thing in frustration and get a new one!
Good luck with it, I'm off to bed
