Are those the Vinpower 4x discs from newegg? I ordered a 10 pack with my LG burner. I've only burned one so far, and it worked fine on my BDP350. The reviews on newegg are generally positive, FWIW.

They're inkjet printable, but not to the hub.

I haven't looked seriously in a couple of months, but I haven't found any hub printable yet. If there's not a technical reason why they can't be hub printable I expect they'll be along presently.

The above link is for a company that approached me about media supply services. I have not yet used them but they do have hub-printable bd-r discs in their online product listing.

Hey,

The discs are "Optical Quantum". The disc info in imgburn said Phillips.

The discs I have made have burned and played fine.

I got up 5.6x speed using imgburn burning an ISO file.

Lets hope the disc prices keep falling as $4 is still a bit steep, but better than $10!

Blu-ray sure does look good.
