還有用LPCM與否是否對聲音有差自己試試看也知道,就試音質,或是動態是否有壓縮 ,我覺得可以自己試試看,說不定別人說沒差,不過你的音響是Hi-end級,覺得有差,一且耳聽為憑,我認為這就是轉檔的樂趣所在 |

NTSC DVD只有LPCM音訊及AC-3, MPEG-1 Layer2 Audio(mp2)並不是NTSC DVD的標準, 並不是所有NTSC DVD player都支援MPEG-1 Layer2 Audio(mp2), 只有PAL DVD才有將MPEG-1 Layer2 Audio(mp2)列入標準. MPEG audio is multi-channel digital audio, using lossy compression from original PCM format with sample rate of 48 kHz at 16 or 20 bits. Both MPEG-1 and MPEG-2 formats are supported. The variable bit rate is 32 kbps to 912 kbps, with 384 being the normal average rate. MPEG-1 is limited to 384 kbps. Channel combinations are (front/surround): 1/0, 2/0, 2/1, 2/2, 3/0, 3/1, 3/2, and 5/2. The LFE channel is optional with all combinations. The 7.1 channel format adds left-center and right-center channels, but is rare for home use. MPEG-2 surround channels are in an extension stream matrixed onto the MPEG-1 stereo channels, which makes MPEG-2 audio backwards compatible with MPEG-1 hardware (an MPEG-1 system will only see the two stereo channels.) MPEG Layer 3 (MP3) and MPEG-2 AAC (also known as NBC or unmatrix) are not supported by the DVD-Video standard. MPEG audio is not used much on DVDs, although some inexpensive DVD recording software programs use MPEG audio, even on NTSC discs, which goes against the DVD standard and is not supported by all NTSC players. |

MPEG-1 Layer2 Audio(mp2)雖然不是dvd格式的標準，
但也很少遇過dvd play不能播的， 至少我試過數十台dvd play，沒有遇過這種狀況。 所以我想不用擔心 你錄mpeg2的格式只能選680*480？ 不能選704*480，或是352*480嗎？ 你可以試試看。 |
