Hmm - I upgraded my Samsung R40 to the latest TSSTcorpCD/DVDW TS-L632D driver today and have not seen this problem since, and it was pretty reliably reproducible before.
Old firmware was SC02, new is SC03. Sadly I had to boot into Windows and I used their upgrade utility at http://www.samsungodd.com/eng/Firmware/FAQ/Faq.asp.
