For this purpose it is necessary to increase video compression, but it will inevitably affect quality: than above compression - that more low quality. Roughly on 1 DVD the disk in volume of 4,7 Gbytes is recommended to be written down about two hours of video (PAl 720x576 25 frames per second ot NTSC 720x480 29.97 frames per second ). In this case video stream is equal (approximately) 4,5-4,6 Mbit/sec, and an audio stream - Mpeg2 224 Kbit/sec To write more - it is necessary to reduce streams of audio and video. For example audio a stream to make 192 Kbit/sek, video a stream - 4 Kbit/sec On quality of audio it will not especially affect. Video and audio stream are specified in compression parametres
