according to your probelm:
you can using software TMPGEnc DVD Author to create a dvd with menu between format vcd and dvd (for dvd, i suggested using DVD SHRINK copy into hdd first), if you add incompatibility format files, TMPGEnc DVD Author will appear a frame, thus you have to convert into compatibile format by other software as TMPGEnc, WinAviConverter and etc

i have no idea, why you have to add a audio file to a dvd, as no image for audio file.That's a stupid suggested that you can convert all dvd to mpg1 file, vcd already is mpg1 file and audio files direct burn into a dvd, as dvd player can play it all, but recomend that you create a ISO file for it before you burning.

p.s想不到上pcdvd也可以訓練自己破破的英文還真不錯 :D

lienly兄您也跑來PCDVD玩啊

Today I tried to use a software called "Apollo audio DVD creator" to make an audio DVD containing 5 CDs. The program is quite simple. It took 3 hours to create the DVD and the result is satisfactory. The size of the DVD produced is about 14% larger than that of the CDs because you have to change the sampling rate from 44.1 to 48 KHz.
Tonight I discovered that I already have a version of "Audio DVD creator" on the HD which was downloaded almost a year ago. At a glance it looks quite promising, there are more options and I'll give it a try this weekend.

alvin0220, I think you should write more to improve your English and watch your grammer. I can't barely comprehend half of what you are writing.

can using --> can use
with menu between format vcd and dvd ???
suggested using DVD SHRINK copy --> suggested using DVD SHRINK to copy
add incompatibility format files --> add incompatible format files
TMPGEnc DVD Author will appear a frame ???
compatibile --> compatible
a audio file --> an audio file
as no image for audio file ???
a stupid suggested --> a stupid suggestion
you can convert all dvd to mpg1 file ???
audio files direct burn into a dvd ??? (directly burn)
recomend --> recommend

Anyway, after more practices eventually you can improve.
