Has anyone installed and actually used with DL DVD media the VS9 Update pack, 8/12/05 that provides DVD-R Dual Layer Support?

TIA,
Erock

I've only burned DVD+DL media, and then using bitsetting to make it appear as a DVD-ROM. I have the patch installed, but don't use DVD-DL media (though I have burned DVD-R disks).

DVD-DL doesn't have bitsetting, and as a result, compatibility of this media will be spotty with anything but the latest standalone DVD players.

Thanks THoff.
My understanding about book type (bitset) was that you couldn't change the bitset on a DVD-R disc as the lead-in area is pre-written when the disc is manufactured, unlike a DVD+R that is left blank. If this is in fact correct, any ideas as to why Ulead choose to provide support for a media type with the least compatability?

I have it installed and use it often. You have to select the media type when you start building in SHARE. It's in an option box. The program does not automatically detect which media you have installed. Maybe this is taken care of in VS10.

Probably because the media exists, and people would ask for support if it wasn't there. Why anyone would use it, I don't know. I only use DVD-R disks for data archiving, but not for DVD Video -- for the latter, I use DVD+R or DVD+DL with a book type of "DVD-ROM".

DVD-R came out before DVD+R, and initially DVD burners supported one format or the other, not both. Some standalone DVD recorders / DVRs still have these media limitations.
