According to Pioneer:
...To make 2X DVD-R record compatible ‘For General’ media, the following steps must be completed before consideration. First, the media must pass the DVD forum’s verification for 1X DVD-R. Once cleared, with the media maker’s cooperation, Pioneer fine tunes the media for 2X recording, then confirms the mass production DVD-R media. Only after passing these tests media is considered 2X DVD-R compatible media.
Due to the use of this development system, depending on the media’s release date, 2X DVD-R recording may not be possible. Unlike high speed CD-R recording, 2X DVD-R recording requires optimization. Without optimization, the possibility exists that the recorded media will lack the desired playback quality. This system has been implemented in order to avoid customer confusion over DVD-R media that is deemed not compatible with 2X recording...
That means that only DVD-R who passed extensive tests with Pioneer can be burn in x2. And today the list of manufacturer who make certified by Pioneer x2 DVD-R is pretty small:
Hitachi Maxell
Mitsubishi Chemical Corporation (Verbatim)
Mitsui Chemicals
Pioneer Video Corporation
TDK Corporation OK
Taiyo-Yuden Co. OK
Matsushita Electric Industrial Co.
That's means all the crap unbranded media will never be supported. Those cheap/unbranded media are probably not even tested by Pioneer even in x1 anyway.
So from now on I think buying a pioneer certifed x2 media is a good guarantee of quality -- of course I'm sure there are already some exceptions to the rule :D
