感謝您的詳細解說
我把所有其他的 codec 移掉了
我的主機板是技嘉的 GA-6VX7-4X
試了其他的 DVD 也有一樣的問題
對了 .. .我剛剛想要把 IDE 的 PIO 模式改為 DMA 模式
但是不行耶 ... 我已經知道在裝置管理員的哪裡改
但是還是改不過來耶

SYMPTOMS
DVD playback performance may be poor if your DVD drive is set to run in Program Input/Output (PIO) mode instead of Direct Memory Access (DMA) mode. For example, in programs such as software DVD decoding, you may experience significant frame loss and/or audio or video synchronization problems.
CAUSE
Both PIO and DMA (also known as bus mastering) are modes of data transfer for ATAPI drives. However, PIO mode consumes more CPU time, and transfers data more slowly than DMA mode. Because of this, using PIO mode for DVD drives can adversely affect performance. Other factors that can also impact DVD playback performance include CPU speed, amount of memory, video adapter and video resolution, sound card drivers, software/hardware decoder that is used, CPU utilization, and the DVD viewing software that is used.
RESOLUTION
To resolve this issue, set your DVD drive to run in DMA mode instead of PIO mode. For additional information about how to do so, click the article number below to view the article in the Microsoft Knowledge Base:

我也試了這個方法

• Change the selection from "DMA if available" to PIO only, and click OK.
• Then repeat the steps above to change the selection to DMA if Available.
但是還是不行改成 dma 模式耶
