Dual Layer Player???
on Jan 27, 2005 at 10:11:09 pm

Do current DVD players support the dual layer format? I am concerned about sending out a dual layer discs unless the majority of players on the market will play them.
Thanks...

All of them are 'supposed to', but that's just like the early days of single layer recordables. I have seen some compatability quotes of about 75%, but it was unclear to me how the disc's were authored and burned--which can have a huge impact on playback. Also the quality of the media (and about a thousand other things). Unfortunately the 'testing' is often anecdotal, or done by those who are very technically oriented, but often not very experienced with creating/authoring discs, mpeg file encoding, etc. I have done several projects using DL media, and have had them 'tested' on about 20 different players so far. I have not had a single problem to date, in fact, the DL discs play well on my 'testing' dvd player (a 1999 portable Panasonic which is very picky). I would however put my experience in the category of 'anecdotal', since I have by no means done wide spread testing. I author on DVDSP 3 and set the layer break there, output to an image file, bring the image file to my PC and use RecordNow to burn the image with a Pioneer AO8 using Verbatim media. The Pioneer AO8 automatically does the bit setting you would want for + media to improve it's set top acceptance and RecordNow fills the two layers with padding data(a requirement for the discs to playback as expected).
