windows7 sp1 wont fit in memorex dvd r 4.7 GB

I use the tutorial in in this web to slipstream windows7 and sp1 but when it came time to burned to the dvd R 4.7GB it told me tha it wasn't enough space on the dvd i went by the tutorial using RT 7 lite 64bit so my question is
Can i shrink it to make it fit? and what can i use to shrink it?
And im going to have to do it all over again because it didn't save an image of windows7 sp1 .

another question im running an intelcore i3 550 3.20GHZ 6.00 GB of ram
and when RT 7 lite was doing the slipstream my cpu was hitting 80 to 95 usage is tha normal?

Thanks for ur help in advanced for any help

i don't know what you did when you slipstreamed sp1, but i can tell you it should fit fine. i have 7 x64 ultimate with sp1 and all updates through 6/20011 on a dvd and it is only 3.43 gigs. if i had not stripped out the x32 it would still be under 4 gigs.

It wont fit buddy, and no, those temps are not normal, try reseatting the heatsink with new thermal paste.

I reseatted the heat sink with "freeze extreme thermal conductivity compound"
And tried it again heres a pic.

I see tha i only got 6 MBs of free physical memory could tha cause my computer to freeze?
Would adding more memory make my computer faster?

I went ahead and did it all over again and still it did'nt fit my iso is 4.49GB after doing a google search someone tha was having the same problem mention tha since its a dell dvd its got extra things in there .And my its a dell dvd and on the dvd it says supported extra languages so what im going to try to do is edit the iso and removed some programs to make it fit .

Ok so i deleted the Langpacks which it was 1.36GB which it brough it down to 3.52GB
and tha solved it .
