How to post-author VCDs?

[kazander]

I recently bought a DVD-standalone. Unfortunately it doesn´t play unauthored VCDs and I already have some mpeg files on CDs. So my question is: is there a way to author a CD AFTER burning the mpg file on the CD, because it would be quite a waste of time and CDs to burn them again...

What model DVD player you bought?

your dvd(unless a cheap one) should be able to play mpegs,check your specs.

to answer the reauthoring question, you can only change data on rw disk.
and you would still have to copy contents to hardrive, author the mpegs, erase the rw, then reburn the disk.

My player is able to play mpegs, but only if I explicitly burn it as a VCD. My problem is that I already have some CDs with mpeg files (but not authorised ones, I just "copied" the mpeg files on the cd! Theoretically I can add folders and files to the CD afterwards, so I should be able to author them afterwards, right?)

Nope, nope and nope.

The data for a MPEG on a VCD is WAY different than a regular burned CD.

First, a VCD stores data in larger chunks and uses space normally reserved for redundancy and error protection in each block to store data. That's why you can store 800MB on a 700 MB disc.

Second, the starting point for the data must be an exact sector.


If your MPEGs are the right resolution, just rip them off the discs, reauthor with VCDEASY and reburn. But I cannot think of any way you'll be able to transform what you have into a viable VCD.
