MP3 Users please read

Has anyone who's using MP3's with CDJ when adding a track to CDJ get the message "Unable to get playing time from MP3 file"? This happens on about 50-60% of the tracks I try to add to the library. The problem exists even with tracks from the same CD. I've tried more than one MP3 ripper, all with the same problem. I'd be interested in hearing from someone who has had consistently good results adding MP3's to the CDJ library and, which ripper you are using. My primary ripper is AudioCatalyst.

Also, if you are aware of a ripper that will append information about the rips to a text file that includes not only the track and title info, but playing time and CDDB ID number. Audio Catalyst does this by using the cdplayer.ini file in windows, but it does not include the track playing time info. If I had a ripper that would include playing time in a text file, I could just write a routine to add the data to the CDJ library using VB6. This would also relieve the user of the tedious task of creating an ablum in CDJ, then adding the tracks one by one. Anyone who's done this for more than one or two CD's knows what a pain this is.
