View Full Version : Prolly OT: how many MB do fit on a CDR in raw mode?

As most of you know a SVCD is burned in raw mode which means that there is no additional error correction per sector as is on a regular data CD. As with an audio cd it is not necessary to have every bit correct cause errors can be interpolated by the player.

OK, now I'm still burning some Buffy eps and they have about 43 mins which is quite a lot of info for a single CDR. I'm using 700 MB/80 min cdrs which allow for about 840 MB of raw data. But how much does really fit on it? Could I use 850, 860? IOW, how can this calculated? Certainly it depends on the type of CDR used? I'm using the quite expensive Verbatim DataLife Plus because of the missing error correction code. Thanks...

I've known some who've been able to get ~920mb of raw data on a cd, and some even more, but it's unlikely you'll be able to get such good results. Once you're at such a high capacity, you have to burn at really low speeds, and take several other precations even to have a slight chance of it working. Better just to use multiple discs ;)

BTW - (to those that care and/or wondered) I have been gone for about a week, without posting, that's because my registry was corrupted by the great quality of the Windows Update! :D So I had great fun reinstalling Windows on another drive, moving all my data from the old hdd to the new one, and then reinstalling and reconfiguring everything (lots of fun, you should try it sometime -_-). I blame Microsoft in every way, but luckily I didn't lose anything critical. So the point of this is that I'm back and hope to post as active as before :)

SVCD isn't RAW mode. It has less error-correction bytes, but it still has some. You can burn ~807MB to a CDR80 without overburn. With overburn it depends on your burner, brand, and last not least, your DVD-player, because not all of them can play overburned CDs.
BTW: Try the search button at the top of this page, and you will find some post about this subject, it was discussed more than one time before.

Welcome back :)

I know it's OT but UltimateDBZ u should really get urself a legitimate copy of Norton Ghost or Powerquest DriveImage. I know what u've been through cause I used to reinstall Windows 98 every two months but with either of these two applications u can do a OS reinstall within 2-3 minutes.

Well, I'd rather suggest him to either

a) get a decent non Micros~1 OS

and/or

b) do not use an online update but download stuff instead

Back on-topic:

I'm quite sure I read somewhere that SVCD IS raw-mode. So if it's not and still has less error codes what kinda mode is it?

I'd like to know how much info fits on a CDR in that mode without overburning. Thanks again.

Sorry, but this indicates you never have read the Newbie reference.
Try this Newbie Reference (http://www.doom9.org/mpg/dvd2svcd_newbieref.html) and your question will be answered.

You're right, I've 'only' read the readme, the posting guidelines and the FAQ. Thanks for the link. Got some question though:

from the link listed above
Adjust the audio bitrate if the total bitrate is too high (Max. total birtate is 2723kb/sec)

Apart from the spelling error is the max total bitrate really 2723 kb/s or 2756 kb/s as said in the bitrate tab?
