"langue" is feminine, so it's "une", & "belle" takes its feminine form to agree, and belle/beau is one of those (few) adjectives that goes before the noun.
The acronym BAGS is useful : Beauty, Age, Good and bad, Size, but beware of "grand(e)". Un grand homme is a great man, un homme grand is a tall man.

Aren't we in danger of getting a rousting from the Mods for going off-topic? Or are they all busy scoffing Easter eggs?

riiiiight hehe but on topic...8x for most media is fine for me or 12x but 20x is pretty much useless for me. Will 20x media be lower quality than 16x or 8x?

Well, exactly. I have a 16x writer but I pick up spindles of 8X media at good prices, the time difference is a few minutes, so I don't care. Fanboys gotta have the fastest numbers on their hardware...

Lower quality.. I would say no. That's because it's all relative to who makes the discs. If you buy Taiyo Yuden 20x discs (if they ever appear) the you're goin to have quality. However, the problem lies in the real capabilites of the drives to keep up with this. The faster you burn, the more likely you are to get errors. Having said that I've seen scans/heard people talk about burning at 18x on 16x media and getting perfect results.

I read somewhere that around 10,000 RPM is as fast as you want to be spinning optical media, and I saw that these 20 X DVD burners go 11,500 RPM. Those fragments will trash the drive... it was bad enough with cheap media and 50X CD-R drives...

Yeah, going back to what someone said earlier in the thrad, there was an episode of MythBusters where they tried to see how fast a disk would spin before it broke and what effects it had on the drive. Needless to say, if a disk breaks up in your drive goin @ 20x, you're new, shiny, expensive dirve is fooked.

glad to see we've reverted to the Queen's English, 'fraid i and probably most of our readers just don't speak or read French.
Anyway, i have seen a cd explode, well heard the sound effects anyhoo. If i recall correctly it was an NT4 install cd that must have been cracked around the hub. A colleague was doing an install via a normal cd drive which was connected temporarily ie ribbon cable trailing across the desk from the PC (hence why it was so loud). Loads of us around the office ducked as it was loud enough to scare the hell out of us. The cd shattered in the drive whilst installing and we had great fun watching hundreds of tiny bits of cd being tipped (or almost poured) out of the drive.
If a disc is gonna go it's gonna go, doesn't have to be at the silly speeds of 20x

The DVD Standard specifies that the case has a release Spider to hold the disk its case. The Spider is the little thing that fits the hole in the disk. Pressing down on the Spider will release the CD or DVD so that it can be lifted out of the case without force. This is a 2 hand operation, the finger of one hand presses down on the spider, the other hand lifts the CD. Many people are unaware that they are supposed to press down on the spider to release the disk. They use brute force to remove it or to put it back. Using brute force causes the disk to flex and bend and results in microscopic cracks around the center that can weaken and damage the disk where it is unable to withstand high RPM speed and shatters.

Mythbusters spun the disc at 40,000 rpm before it exploded. The fastest drives only go to 11,500 rpm, the theoretical limit because at speeds faster than that the disc begins to oscillate. Oscillating prevents the laser from proper focus, and a drive will reduce speeds in order to focus better.
Discs can shatter at speeds well below 10,000 rpm if the hub is cracked. The sandwich construction of two 0.6 mm plastic halves is susceptible to cracking one or the other half--or both--in a standard jewel case tray rosette. That's why the DVD tray design described by Indochine is different from that for CDs.
A drive reaches its fastest rotational speed at the beginning of the disc recording and usually slows down from that point on. A 20X drive keeps the rotational speed at or near the maximum theoretical 11,500 rpm throughout the entire recording. It may be that oscillation is still a factor because I have found only three discs that "work" at 20X, and all three have excessive PIE/PIF errors toward the end of the recording at the outer edge.

Just a question here, not trying to pick you up, but why then, does me drive speed up during the data verifaction process? Obviously it's not the same proces, but I figured the same thing applied..

During verification, the drive operates pretty much the same way as burning except that it is also looking at the data tables to make sure the file addresses match the placement of the files. Since the file addresses are toward the inner part of the disc, it pays to keep the disc spinning at a high rate of speed so that the optical pickup head can look at the addresses quickly and go back to the files.
The speed rating of a drive is its data transfer rating, not the rotational speed of the disc. Think of a bicyle wheel: it hurts more to stick one's fingers in the spokes near the rubber tire while it's spinning than to stick them in the spokes close to the hub. That's because the outside part is moving faster than the inside even though both are at the same rotational speed. For a 52X CD-R the data transfer starts at a fast rotational speed--10,600 rpm--but the data are going only at 24X. The data transfer works its way up to 52X as it applies more laser power; but since far more area is being covered toward the outside of the disc, the rotational speed does not have to change--it stays at 10,600 rpm. (You can verify the difference in area easily. A disc that is half full looks as though two-thirds of it has been recorded on the bottom. That "last third" is actually half the area of the disc.) Nero CD/DVD Speed also shows the difference in its recording scans. The default green line is the rate of data transfer; the yellow line is the rotational speed of the drive.

once and for all i will find the linear velocity of particle at very edge of the dvd:
so taken 11500rpm(?) for 20X:
11500rev/1min * 2pi=72220 rad/min
72220 rad/min * 2in=144440 in/min
= 137mph
so NOT SPEED ON SOUND.

who cares about 20x,they can make it a 100x !!!!!..the best burning speed is 1/2 the rated speed of the media your using..thats for video_ts and data files..less errors..
16x media=8x burn=7min
8x media 4x burn=8.5min
edit
getting tired

oh yes oh yes no big difference. (btw cool to see u around, dvdxcopy is how i found this site couple years back)
just to get even more clear about those calculated numbers, note thats a laser at 20X CLV reading the most outer particle on disc. so if 20X CLV reading anywhere towards the center of disc then the speed it turns at the particle caluclated above would go even faster!

Hey,
20x is for salesmen to have something new to sell :D
I burn all my stuff at 4x and will not go faster any day soon !
Taiyo Yuden and Verbatim media, nothing else.

hey cougar. even i stick to 8x these days (apart from these less than excellent MCC004 which have to be cooked at 4x)

Ya, what's up with that !
Verbatim 16x lack their usual quality ?
Your not the 1st one to tell say this, that MCC004 are not as good as MCC03.
I burn everything at 4x so have no noticed a difference between all the media that I use:
MCC02 / MCC03 / MCC04
TYG01 / TYG02 / TYG03
