[資源]相容HD-DVD與Blu-ray Disc的video encoding參數

HD-DVD的VBV buffer size
來源: https://forum.doom9.org/showthread.php?p=881160#post881160
According to the HD-DVD specs, these are the allowed VBV buffer sizes:

1843200 bytes for Main Video HD
937984 bytes for Main Video SD
929792 bytes for Sub Video HD
242688 bytes for Sub Video SD

So it looks like the buffer size is more like 500 msec, not 320 msec.
