using XCDroast Version 0.98Alpha10 on Mandrake 8.2 with a TEAC CD-W516EB (16x burner)
First I have seen a bunch of messages over the last few days complaining that the ISO images are too big, some info is needed here for people.
that size you see is not just the data of that image, its comprised of a few parts.
Lead in track
TOC
Data track (In mode 1 there is only one track, in Mode 2/XA there could be multle tracks)
Lead out Track
so when you look at a cdr blank, lets say 80m/700meg cdr that 700 meg is for data, what is not shown is TOC, leadin/leadout sizes.
a typical TOC for a ISO9660 disc is 23meg and 15meg for every track after the 1st, in the case of Mode2/XA disc's
A full description of what happens is documented in the Yellow Book for CD by Phillips.
(Note I prob do not have the absoulute correct method for ISO9660 described here, couldn't find my docs, did it from memory)
Secound, burning with XCDRoast
be upto date, make sure the XCDRoast is current, this is a must, as support for newer burners are always being updated.
in XCDRoast go to "Create CD -> Write Tracks" on the right side under parameters is a switch for Overburning, also there is selector for choosing 74 or 80 minute media.
Third, choosing a burner
I don't want to start a war here but I have gone through several burners since I got my first one.
HP ( Had the 4020i, went through 5 of them)
Yamaha ( have both 426 and the 8424 scsi, both worked flawlessly)
Teac ( have TEAC CD-W516EB, First IDE, in my main Linux, works flawlessly, use XCDRoast for cutting ISO)
Plextor ( have 16/10/40a, Works fine, use in my windows enviroment, have cut Mandrake ISO no prob with CDRWIN)
LiteOn ( have 40/12/48, Best burner I have, Works flawlessly including all RAW DAO modes and 90/99 minute cd's)
( Have used CDRWin/NERO/CloneCD and have cut all Mandrake cd's from 8.0-9.0 versions)
My Teac/Plextor/LiteOn all have Burn proof systems and is supported in XCDRoast
I have seen here that a major amount of problems seem to occur with HP 8200/8700/7xxx Burners, and I have seen many a complaint over those models of HP burners.
By the way burning slower in not always good, if you are using the colorless/near colorless media such as,
Disk sub type: Medium Type A, low Beta category (A-) (2)
ATIP start of lead in: -11634 (97:26/66)
ATIP start of lead out: 359849 (79:59/74)
Disk type: Short strategy type (Phthalocyanine or similar)
Manuf. index: 3
Manufacturer: CMC Magnetics Corporation
Blocks total: 359849 Blocks current: 359849 Blocks remaining: 60143
They are not intended to be burned at less than 4x, this can cause errors, if you want to burn slow you need the disk type with long strategy type of dye.
In Canada, a LiteOn bare bones oem drive (40/12/48) is $95CDN or a retail 48/12/48 is only $120CDN, so it's pretty cheap to replace a burner.
Here is a complete output from XCDRoas cutting Mandrake 9.0 ISO cd2 from my TEAC on Mandrake 8.2

there is two tools that comes with cdrecord/mkisofs
isoinfo and isovfy
use these to check out ISO images to stats on them.

I Hope this helps some people who are having dificulties with the ISO Images of Mandrake 9.0
