So how so I do that? The video that I want to include will occupy not more than 50% of the disk space. The rest of it will be audio data. An audio player could or could not ignore the video (MPEG2 stream), it has no importance. But it should recognize the audio track. A DVD player should perform both tracks (both video and audio).
Making a black MPEG1 file with a high quality sound that I want to include could be a solution. But then it would not be compatible with standard audio CD players.
BTW, is there any way to continue a data CD with a CD audio track? Nero always demands to insert a blank recordable CD and rejects an already used one.
