99min = 870mb, iirc
i think its not fake, but u must make sure ur cd-writer support reading/writing 99min cd-r, else it would just recognize the 99mb cd-r as standard cd-r.

there is no such thing as cd-r and cd+r lol
the + and - thingy only available for DVD.

depend on brand iirc, if u wana test ur dvd combo overburning capability, go http://www.cdspeed2000.com/ download cd-dvd speed,
and run the overburning test with ur 99mins cd-r.

seriously, what software u use to burn those 99mins cd?
and as far as i know. only Nero can do overburning, and, ur DVD combo must support overburning too.

actually here is how i do overburning.
1. buy 99mins or 800mb cd-r(of course u can use stardard 80mins/700mb, but thier overburning capability is depend on brand, mostly can only extend to 710mb iirc.)
2. run overburning test by using cd/dvd-speed2000 to get the max overburning capacity support by ur CD/DVD writer, and the media.
3. finally can buring cd/dvd with nero.

last time i successfully write 4 video files, total 771mb to 99mins cd-r(cap ayam brand, its called "melody") with my oem LG cd-writer, nero finish it without any error,
but my cd-writer cant read the 4th video file properly, end of story

yup, i check the disc quality with cd-dvd speed after bought it, damaged sector is more than expected, and it use lime color type dye, usually cap ayam branded cd-r will use this kind of dye.(verbatim/mitsubishi usually use blue color dye.)
forget the real manufacture already

dvd writer/HDD and the medium now is very cheap liao, dun waste time on how to overburning cd-r/w
or u will ended up the same fate as me, since overburn-ed cd-r is not standard cd-r anymore, u can create it but that doesnt mean u can use it without any problem.
