Yes, of course i've done this before!  

But suddenly I'm having a ridiculous problem that i don't understand, and just wanted to pick your collective brains about it, if i may...
I have a blank 80 minute/700mb CD-R.
I created a playlist that is about 70 minutes (cant remember how many Mb, but it was much less than 700).  
When i click on 'burn disc', i get a warning saying that this playlist will not fit on the CD.
I thought that was kind of crap, but managed to cut another couple of songs, and still get the warning that it will not fit on the disc.
I cut more songs... got it down to a lame and ridiculous 9 songs  -- only 35 minutes of music.  And still the bastarn thing is giving me the 'your playlist will not fit on the disc' message.
I don't get it!   

And I'm not amused... 

What's going on here... any ideas?
