While burning SVCD, MPG file gets bigger

[Crunk]

My original source file is 783 MB and when burned onto a CD, the file is 793 MB. What is the reason for that? Thanks.

That's normal.
A DAT (the mpeg at (s)vcd) is the MPeG + some CD CRC-checking codes.

So it's not necessary to save the original mpg file? If not, then i've been wasting a lot of discs, but to make myself feel better, it's so that if one of the CD breaks, i'll have a copy!

No,
As soon you've tested the burned (S)VCD -- test it in your standalone DVD player at your TV, or at your PC in a DVD-player - you can delete the original MPeG from your PC.

In the future, whenever you want to have a copy of the MPeG (originally it's a DAT), then use tools like webFlix or VCDgear to convert the DAT to MPeG again.

Thanks, one thing though, I just checked an (S)VCD that I made and the file itself is already an MPG, so there's no need to convert. I was just wondering when it's a DAT? Thanks...

its a Dat file if its VCD, SVCD has the file extension .mpg, but it still need to be converted to a proper mpeg file, before you can use it properly.

I see, lol sorry, but what do you mean use it properly? If you can, please post how to convert it too (Or is it what Betamax said?). Thanks.

If you want to edit or re-encode the mpeg then you need to put it through VCD Gear which is a small and easy program to use, you should be able to work it out if you need to use it, if its a VCD file then use the convert Dat to Mpeg option and if its a SVCD use the mpeg to mpeg option.
