DVD Emulates Audio CD?
Is it possible to burn audio tracks to a DVD+/-R in the same way as to
a CD-R. ie not creating DVD-Audio just CD-Audio utilising the greater capacity (and NOT the extra mhz etc) which could then be read by my DVD player (Pioneer NS-DV55 if at all relevant) as a normal Audio CD is? I have searched and searched the net and usenet and can find no answers. TIA Moldy |

I have searched and searched the net and usenet and can find no answers. The basic answer is "No", to the best of my understanding. The cause is the very different data structuring of the two media. At a fairly low level, CDs are organized into small "frames" of digital data, with synchronization and subcode and parity information added to the 16-bit data samples. Higher-level structures (blocks and tracks) are created by aggregating these frames together. Reliable data storage (for e.g. CD-ROM style data) is "layered" on top of this aggregation. There's a special "table of contents" area prior to the beginning of the first track, where the track structure is described. DVD media was designed from the get-to to behave a lot more like a traditional data-storage medium. The data is organized on the disc into 2048-byte blocks (rather than small audio frames), and there's no special reserved "table of contents" area. Basically, a DVD disc just looks like a computer filesystem (typically a UDF filesystem) which stores data files. Audio data, etc. is stored in these files. Due to the difference in data formatting, I don't think it'd ever be possible to _exactly_ reproduce the structure of an audio CD on a DVD disc. The closest you could come, probably, would be some sort of filesystem with a bunch of .WAV files containing CD-quality/formatted data. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
