[QUOTE=CookieNL;2273287]I think I am going for the Verbatim 16x DVD-R (MCC 03RG20) type
because the DVD-R format is more compatible with DVD-players than the format DVD+R. Just to make ensure it works on different DVD-players.[/QUOTE] You can increase compatibility of DVD+R media by using a technique called BookType bitsetting. This is a way to “fool” most DVD players into thinking a DVD+R disc is really a DVD-ROM.
You can do this on your NEC ND-4571A drive by flashing it with one of the unoriginal “bitsetting” firmwares available here and then use one of several tools e.g. binflash to enable bitsetting for DVD+R media.
Using bitsetting for DVD+R makes such media approximately as compatible with old DVD players as DVD-R media; some will play DVD-R but not bitset DVD+R and some will play bitset DVD+R but not DVD-R - most will play both.
My other question is about the burning speed you already mentioned.
A lot of people are saying that the best burning speed is 4x so you do not get many errors.
But you do not recommend burning slower than 6x?
So what is the right burning speed? :o
Don’t believe everything you read on the internet - not even here at CDFreaks!
There are very few cases where modern 16x+ DVD burners with 8/16x DVD media produce better results at 4x or 16x than at 6x/8x/12x. Such cases exist but they are the exception and not the norm.
I don’t have your drive model, but I have earlier and later NEC/Optiarc drives, and I can’t think of an example where 4x produced better results than 6x/8x with those drives and non-rewriteable media.
I suggest you forget about 4x burning unless you want to spend the time necessary to burn at several speeds and perform Disc Quality Scanning tests on the burned discs.
In most cases 8x will provide a nice balance between speed and reliability, but 12x is usually OK.
16x is too fast unless you are sure you have the best possible batches of premium media, and even then the “quality” of the burn will almost certainly be better at 12x or 8x.
In a few cases 6x can be slightly better than 8x with the NEC/Optiarc (and other) drives I have used.
