Для DVD-плееров в каком формате лучше писать диски: MPEG2 или DVD?

Стандарт DVD использует MPEG-2 видео, но определяет некоторые ограничения:
Допустимые разрешения
720 × 480, 704 × 480, 352 × 480, 352 × 240 пикселей (NTSC)
720 × 576, 704 × 576, 352 × 576, 352 × 288 пикселей (PAL)
Допустимые соотношения ширины к высоте Aspect ratio (Display AR)
4:3
16:9
Допустимое число кадров в секунду
29.97 к/с (NTSC)
25 к/с (PAL)
Note: By using a pattern of REPEAT_FIRST_FIELD flags on the headers of encoded pictures, pictures can be displayed for either two or three fields and almost any picture display rate (minimum 2/3 of the frame rate) can be achieved. This is most often used to display 23.976 (approximately film rate) video on NTSC.
Аудио и видео битрейты:
Buffer average maximum 9.8 Mbit/s
Peak 15 Mbit/s
Minimum 300 Kbit/s
YUV 4:2:0
Additional subtitles possible
Closed captioning (NTSC only)
Audio
Linear Pulse Code Modulation (LPCM): 48 kHz or 96 kHz; 16- or 24-bit; up to six channels (not all combinations possible due to bitrate constraints)
MPEG Layer 2 (MP2): 48 kHz, up to 5.1 channels (required in PAL players only)
Dolby Digital (DD, also known as AC-3): 48 kHz, 32—448 kbit/s, up to 5.1 channels
Digital Theater Systems (DTS): 754 kbit/s or 1510 kbit/s (not required for DVD player compliance)
NTSC DVDs must contain at least one LPCM or Dolby Digital audio track.
PAL DVDs must contain at least one MPEG Layer 2, LPCM, or Dolby Digital audio track.
Players are not required to playback audio with more than two channels, but must be able to downmix multichannel audio to two channels.
GOP structure
Sequence header must be present at the beginning of every GOP
Maximum frames per GOP: 18 (NTSC) / 15 (PAL), i.e. 0.6 seconds both
Closed GOP required for multiple-angle DVDs

задай себе вопрос, а в чём их отличие?)))

ну сам практически и ответил на свой вопрос прочитав инструкции.
