help choosing programs ...

1- for burning MP3 CDs and ISO i use Roxio Creator 2010 Pro
it does the job but it is kind of heavy and slow ( 3.34 GB )
so what's the best and lightest program for burning ?

2- for playing media i use media player classic with the k-lite codec pack
it's great and it can play anything but "RMVB" ... so i had to install realplayer
is there any player that can play everything ?

kak2a2,

Roxio Creator 2010 Pro is indeed a heavy application, making it slow to install and utilize. I advise you to uninstall Roxio, and then download and install ImgBurn. Most people here in SF highly recommend that app because it's lightweight and fast.

Media Player Classic with K-Lite is a great combination, but you can try out VLC media player or Shark007's Free Codec solutions. Most people use and recommend those as well.

can it make mp3 CD's ?

Yes. :)

ImgBurn is a lightweight CD / DVD / HD DVD / Blu-ray burning application that everyone should have in their toolkit!

i just added the real alternative codec to the media player classic and everything is solved now
thank you guys : )
