CDRInfo tests for the first time, the DVD-R DL format with two well known recorders from Plextor and NEC! We tested the Plextor PX-716A and NEC ND-3520A with Verbatim/MKM 4X DVD-R DL media, and the test results can be found over here. Shortly, we will update our test results with Pioneer DVR-109 drive burning the MKM DVD-R DL at 6X! Stay tuned!
