how do I get gapless playback on self-made ripped CD comps?

Vorbis is inherently gapless. MP3 is NOT inherently gapless. MP3s cannot play gaplessly unless (1) you use the LAME encoder to encode them, and (2) you have a player that knows how to read the header information that LAME inserts, which allows the player to skip the gaps that are inherent in the MP3 format.

And the winner is ... Febs!
:P
EDIT: What bitrate were the MP3's that were burned to the CD in the first place?

Thanks for all the advice;

Burning with Nero, say, allows me to edit, fade-in / out as well as crossfade.
Also, how will the quality be degraded?

Read the part about lossy compression.

Chronon:
I'm going to hazzard a guess here. It seems to me that the gaps come in when the mp3s are converted to AudioCD. All of the header information is probably lost then. If it only plays well through your DVD player with crossfade on then it sounds like gaps have been introduced.
Now when you take this CD and re-rip it with LAME you may not get any extra gaps but you 'might' have gaps that were picked up by the first conversion... plus, as someone said, the quality will be degraded from the original mp3.
I'm no expert in this. Does anyone know what happens when you do this:
LAME mp3 --> AudioCD (WAV?) --> LAME mp3 ?

You get an MP3 that is of lower quality than the first generation MP3.
