DVD Video / Audio and decoder problem:
Go to "Options" menu -> "DVD Settings", manually choose a DVD Video and Audio Decoder, for example [ CyberLink Video/SP Decoder, CyberLink Audio Decoder ] or [ InterVideo Video Decoder, InterVideo Audio Decoder ]. It is recommeded to use both video and audio decoders of the same manufacture instead of mixing two different brands.
If you use Nero 6 DVD decoders, you may update to the latest version for the best result.
If you don't have DVD decoders installed or your decoder does not work well, you may download and use MpegDecoder012 (for video) and/or AC3Filter (for audio) as your DVD Video/Audio Decoder.
Key Exchange Failed:
Try to exit the program and run again. Or upgrade to DirectX 9.0c. For further information see this article. You may try to select a "DVD Navigator" other than "Microsoft DVD Navigator" in the DVD Settings dialog. If you still experience the problem, download and install DVD43.
DVD parental control:
If you cannot play some DVD due to parental control, please check and make sure your Windows Media Player can play the DVD correctly. For more information please see http://support.microsoft.com/?kbid=297733 . Note: you need an administrator account to change the settings if you get this error.
DVD subtitle(subpicture), language:
It is recommended to use the native DVD menu in the preview panel to set subtitle(subpicture) and language. (Click "DVD menu" button on the right to show native DVD menu in the preview panel) You may also change the subtitle(subpicture), language in the program's Options menu, but there are some DVDs that require the change must be made in the native DVD menu instead of the program's menu.
Video file does not show on PSP:
Make sure your video file name follows PSP's special convention. e.g. M4V12345.MP4. (You can change the "file number" in Output Settings dialog). Other file names are not recognized by PSP.
RealMedia, MOV format:
The support for rm / rmvb video file is experimental. If you installed some software component (e.g. Moonlight Player) and have difficulties in recording rm / rmvb files, it is recommended to uninstall such component first. MOV verion 1 and version 2 are supported. Some MOV files can not be played in Windows Media Player, thus they are not currently supported by our product as well.
Ghosting Effect on PSP screen
Ghosting visual effect is subjective. Some people are more sensitive to this visual effect, expecially when the picture displayed is in dark scenes. This is because the refresh rate of a PSP LCD screen is lower than the rate of a normal PC monitor. When the PSP video is also in the low fps (15 frames per second), some people may see ghosting effect. In this case, try to convert PSP video using 29.97 fps settings (in the Option menu -> Output Settings) to reduce this effect.
