I tested:
Blu Ray movies in original and burned (backups) = 1a
Music CD's in original and burned (backups) = 1a
DVD's in the original and burned (backups) = 1a
Mp3's from 4GB USB Stick in various. Folders = 1a
various. data discs with mixed content in AVI, WMA, MP4 format = 1a
Upscaling of DVD's = 1a
Image and sound quality = 1a
The Start and read-in of the drive = 1a (10-15 sec.)
Drive rest = 1a (quieter than my PS3)
The remote control 1a = small and good transmission power, just can not drive my TV
A minus was for the external power supply .... not just looks great when it lying around outside.
Sorry if that was not enough for some .... I've had enough just with a Blu Ray player to do that for what it is actually meant .... Blu Ray, CD's and DVD's :-)
The price almost unbeatable .... !!!
Nevertheless hope it was helpful for one or the other.
