<< DVD-A == DVD audio i pressume? >>
Yes, not DD or DTS, it's 6 channel audio.
The Panasonics are also CD-R/RW compatible (which can be inferred from the MP-3 capability).
A progressive display draws every line of a frame with each scan, as opposed to an interlaced picture which draws every other line on the first scan, and then fills in the skipped lines with the next scan.
A progressive display is much clearer, brighter, and sharper than interlaced.
Your computer monitor is progressive, while a standard TV is not.
