Any specs on MATSHITA DVD-RAM UJ-822S ?

[alpuzz]

I got this drive with my T43 2668-75U. I understand from reading other threads here that T43s have been shipping with a drive that burns DVDs at 2x, but that Lenovo was going to start shipping a faster drive. So, which did I get? Also, are there any detailed specs as to which formats this drive will handle, etc?

Thanks,
