I tried to burn a music CD in Toast but it only burnt 70 odd songs! I have a MP3 player in my car and I want to burn an audio CD made of songs from other CDs (about 120 songs). I tried to do it itunes but it wont let me burn .mp4s or such. Am I doing something wron?
No, you're not doing anything wrong.
As for burning part of your concern, when you go into iTunes preferences and set the burning mode to "MP3 CD" keep in mind that all this does is it filters out any files in your playlist that are NOT MP3s (e.g. AAC, WAV, AIFF, MP2, video files, etc.).
All the files that are not MP3 format are not changed or converted on the fly. They are simply left out. Songs bought from the iTunes Music Store are definitely NOT converted to MP3 on the fly.
MP3 CD players usually don't play AAC (or .mp4) files, so that's why the filtering is necessary. That basically means if you want the non-MP3 songs to play in your MP3 CD player you have to convert them yourself. To do that, you can hit COMMAND + J and check to show the column "Type". Sort by this column, and any file types that are not beginning "MPEG Audio" can be highlighted, and under the Advanced menu you can select "Convert selected tracks to..." Make sure Importing preferences are set to the MP3 encoder. The only catch with this approach is iTunes won't let you convert iTunes Store songs to MP3, at least directly (I'm guessing the DRM Free songs wouldn't have this problem, but I wouldn't know).
Once that is done, you can move the new converted files to the playlist, and delete the old ones. Then you will have a nice MP3 CD.
Does that solve your problems, or does that open up a whole 'nother can of worms?
