Envee IFE_cd-i

Hi, not sure whether you are still working on the project. I work at Envee Inflight Entertainment, our team has worked out the cd-i project(just with audio content). we solve the problem with the combination of software and hardware. just for the audio content, record the audio->convert the audio into certain format(encoded in ADPCM)->then burn the disc (CDR is good). if there's anything we can do, leave me a message.
