Medieguiden

Der er et fint lille program: DVDINFOPRO, http://www.dvdinfopro.com/

som jeg har brugt til at måle på en Princo DVD-R skive. Jeg har 2 drev (en dvd-brænder og en dvd-rom) i min PC.

Her er resultatet fra brænderen:

Her er resultatet fra DVD drev'et:

Som det ses understøtter rom-drevet ikke Media Code, men brænderen gør. Men måske et nyere dvd-rom drev kan, (mit er et ældre Toshiba SD-M1502 drev. Programmet kan også afsløre read errors på brændte medier. Det kan være brugbart hvis man vil vide om det er mediet eller afspilleren som giver problemer.

Smart program og gratis
