"comes up as a cd drive", did you try to remove/delete the drive entirely and reboot?
" HP dvd740 ", did you check for a firmware update, new drivers?

ensure that your driver's are ok for that hardware.

hi, try booting to cmos setup check the configuration if your system can read it correctly as dvd, if your your system doesn't read it correctly, try using other data cables..

I had a similar problem, only it was solved by reinstalling Windows and my "CD drive" was able to read DVDs (as they were 4.8 Gig CDs). I had no autoplay functionality in a sense of playing Audio CD's or DVD Movies. Only data CD/DVDs worked normally (autoplay). And it also registered as CD drive. I found that part of the problem was with windows registry regarding CD protocols. It was missing a service called "red book". ("Red book" is a name for audio CD standard) That is why I had to reinstall the windows.

You should have in mind that DVD drives have 2 sets of lenses. 1 for CDs and 1 for DVDs. It is possible that DVD lens is not working, got dirty or something, so your drive (old one) is being able to read CDs only. New one might be ripe for RMA if the case is the same.

If you have Nero at your disposal, there is a little utility called Nero Info tool. I believe that it is available for download as standalone program. It will display all of the capabilities of your drive, among other things, plus it bypasses windows drivers and settings.

Also, there are drivers (ASPI drivers - responsable for all CD/DVD reading and burning) that tend to get corrupted (overwritten) by some media player installations. There are tools (forceASPI, fixASPI...) that can fix those, but you would have to know your ways around PCs to be able to use most of them.

Are u sure about the above fact. I have never heard so. the read assembly has only one lense. I have a laptop with a push in DVD Writer only one lens is there.

Well, that's what I've picked up while troubleshooting my problem. Maybe the lens itself is universal, but the technologies are too different to be compatible with single lens + optics. Allot of people have faulty DVD part of the burner, and they still can use CD part without any problems whatsoever. That is typical symptom of bad DVD lens (or something).
