a shortage and some comments

This burner should replace the internal DVD drive of an older MacBookPro. The USB ports of the computer proved to be too weak, the burner always need a separate power supply. On a hub with an external power supply he was running smoothly.

My two firing tests each lasted between 1 1/2 - 2 hours which is sorely slowly.

It is also interesting that Apple's DVD player from home only controls the internal burner, you can change how it goes well, is somewhere on the net. VLC recognized inserted DVD without hesitation.
