I have an internal LG 10x Blu-ray burner in my 2009 Mac Pro, which I bought online from OWC (part no. LGEWH10LS30KMP) and it works perfectly. It has LightScribe, which I haven't used yet, but I've burned many BD-R discs without a single error or problem. I've been exporting copies of a feature film I worked on, and final output is 105 minutes, 1920x1080/24p Blu-ray, using Adobe Encore.
Not sure if you have a PC or a Mac, but here's a link to OWC:
I'll second what WonderSpark said about the LGs, and add that Verbatim discs round out the combo.
Haven't gone wrong with that combo yet. I'm using a PC: Premiere Pro > AME > Encore > IMG file > disc
Best of luck,
Yes, I only, ONLY use Verbatim discs. I've had errors on other media such as Memorex, and others I can't recall, but never a problem on Verbatim. It has to do with the dyes and manufacturing used. I've also had good luck with Phillips burn media that a client provided, but I told him to buy Verbatim in the future. You'd think I get paid by them or something, but I just love their product, hahaha.
I also have had good luck with my LG BluRay burner.
I have heard bad stories about Memores (disks go bad after 6 months).
So far, I have had good luck with Kodak ink jet printable BD-R. I haven't had a bad burn and they are still good after 6 months.
