First of all, thank you guys for this useful informations. You are right, no drivers needed, windows is absolutely able recognize the TS-H552U. It took me years to accept, that everything in a computer needs at least one driver, and now this! And okay, Samsung doesnÂ´t belong to the axis of evil, at least not his ODD-department.
But after all, the driver still only works as a simple cd-rom drive. Either it cannot play dvdÂ´s, nor it can burn them. OK, this is not nice, but what even sucks more is, that it is not able to burn data- or audio-cdÂ´s. The software - pinnacle/ steinberg - keeps on reporting me: No recorder found.
The PC is a Athlon 2000+ System and I payed for it about $ 300, what is pretty cheap, for it came with 2 HDDÂ´s, 768 Ram, good graphics and - of course - the Samsung DVD-Recorder. I bought it primiarly to have better performance for Hard-Disk-Recording and other musical purposes. But it doesnÂ´t work really properly, there are some problems f.i. MIDI-delays whilst recording etc. OK, I get used to it.
Maybe sometimes it is more expensive to buy cheap things.
