Professional DVDs...

I was informed earlier that actual DVDs made by DVD companies have more memory, and several layers versus the consumer DVD-Rs that only have one layer and therefore can only have 60 minutes of top quality DV on them. Are these other DVDs available to the average person, and if so, where do you get them? How much do they cost? And can you use a normal consumer DVD writer to fill them?

Just keeping this alive... Com'on, someone has got to know something about this?

I never knew that, im slowly getting into DVD creation but right now I don't have a clue.

My advice is, don't make a feature film! LoL.

I'm not 100% about what DVD Writers can & can't do... but here's a good place to start looking!

There are details about DVD-R, DVD-RW, DVD+R, DVD+RW

I have no idea what the differences are between the '-' and the '+' though?!

I'm slowly learning about the process of transferring DV to DVD and it's a minefield!.Discs available for DVD burners have only one side opposed to dual sided commercial discs. I have read about some users being able to burn 90mins of HQ video to a DVD but this is by messing around with the bitrates. So a lot of setop players just spit them out. I suggest going to www.computervideo.net and going to their self help message board. It has a MPEG, DVD section. Alot of the users already have DVD burners and i'm sure their help will be invaluable.

Hmmm. I got an answer from dvdrhelp.com. Apparently, the commercial DVDs are actually several normal DVDs burnt separately and then pressed together.

Cool. Thanks.

Hi,

Most commercial DVDs are dual layered. Effectively like 2 discs pressed into one. The DVD-RW drives that come as set-top units or as drives that fit into computers only write to single layered discs. These discs hold 4.7GB of data, which roughly works out at 2 hours of video per disc. This is a variable figure though, as you can have different data rates for your video. There is a trade-off between quality and length. the higher the quality of the video the less you get on a disc, and the lower the quality the more you will fit on a disc.

Hope this Helps
