dvdauthor 只能有 128 条前置、后置和单元命令

Question

我创建了 bash 脚本，将我的音频 CD 存档存档到带有菜单的 DVD 上。结果 dvdauthor.xml 包含艺术家列表的标题菜单和带有艺术家歌曲列表的 9 个菜单。共有 67 首歌曲。

<dvdauthor jumppad="0"><vmgm><menus><video format="pal" aspect="4:3"/>

因此，标题中有 67 个“前”命令，菜单中有 9 个。标题中有 67 个“后”命令。总共有 143 个，超过 128 个。DVD 播放没有问题。但如果我再添加一个包含 7 首歌曲的菜单，就会出现“ERR：前、后和单元命令只能有 128 个命令。”

然后我重新编写并从所有标题中删除“pre”。然后我有 10 个菜单，标题中有“pre”和 74 个“post”。图块中没有“pre”。现在是 84，小于 128。但我收到相同的错误“ERR：只能有 128 个用于 pre、post 和 cell 命令的命令。”我有 74 个带歌曲的按钮、10 个“随机播放”按钮和 9 个“后退”按钮。一共有 93 个按钮。

“ PGC 的<pre>和<post>部分加起来最多可以包含 128 条 VM 指令”。如何计算指令？

补充笔记

我改变了

<button name="shuffle">g0=0; g1=0; g10=1; g11=random(8); (...) if(g11==8) jump vmgm menu 9;</button>

本身和 dvdauthor 接受额外的约 10 首歌曲

<button name="shuffle">g0=0; g1=0; g10=1; g11=random(8); jump vmgm menu 1;</button>

接下来我尝试修改所有 70 个标题集标题中的“pre”，但似乎没有效果。

<pre>g11=0;</pre> --> <pre>g11=0; g3=random($num);g4=random($num);g5=random($num);g6=random($num);g7=random($num);g8=random($num);g9=random($num);</pre>

我也尝试过在每个标题集菜单中跳转，但无法自动激活命令按钮。

最后说明

我编写了一个脚本，如果使用 2 个屏幕选择艺术家，它将接受 99 首歌曲。奇怪的是，在这种情况下，前/后的数量比一个艺术家选择屏幕的数量还多。以下是缩短的 davdauthor.xml
