試試以下方法,不過本人的535K由經銷商改機時,應該已經解決一區RCE問題.(機器將全區片當成一區來解碼,換VCD片則當成三區)所以無從驗證,也請讓大家知道這方法是否有效.(需要無RCE的一區片)

引用http://www.dvdtalk.com/rce.html所言:
Are there workarounds for RCE Region-Free or Code-Free DVD players?
A: RCE does affect these players but there are work arounds:
1. If your player has manual Regional Switch capability, then use the manual switch and set it to Region 1.
2. If this doesn't work, play a non-RCE Region 1 title for a few seconds, and then put in the RCE title.
意謂
1.若播放機有手動區碼切換功能者, 調整為第一區.
2.在全區機置入無RCE的一區片,播放數秒鐘後再改放RCE片.
