1. The sound of the movie is very soft or there is too much noise.

This occurs where there is a problem in the settings of AC3Filter installed in your PC.

Click [Start]-[Programs]-[AC3Filter]-[Configure AC Audio Filter]. When the option window pops up, set [Output]-[Speakers] to '2/0-stereo' and [Sampling] to 'PCM 16-bit'from the 'Main' tab.

When the sound is too soft, turn the master volume up from [Gain Control] and when the voice is soft, turn the voice volume up.

2. There is no sound.

This is generally caused by a missing audio codec, and it should be addressed by installing the right codec.

For the information on the recommended codecs for Play@TV™ NMP4000, refer to the list of necessary codecs and files on our site.

3. When playing a video, the forward and backward buttons do not work.

When the forward button and backward buttons on the remote control do not work while playing a video file on Play@TV™ NMP4000, any of the following may be the cause.

1. The length of video is less than 30 seconds

2. Video length is set to be 0 while adding a video to Media Organizer.

3. The installed codec displays the file info as a file that can't perform seek function.

For situations 1 and 2, press the [INFO] button on the remote controller to see the total length of the video.

For situations 2 and 3, install the latest version of the required codec. After reinstalling the codec, remove the video file from Media Organizer and add it again.

4. When playing video, the frame skips and there is noise.

Check the CPU usage of your PC.

The frame skips because of the CPU's low performance. If you want to check the CPU performance, press Ctrl+Shift+Esc in order to open the Windows Task manager and check the CPU usage graph. If you see the CPU usage often reaching 100%, it means that the CPU lacks performance.

Check if the CPU of your PC can play the video file.

1. Search for the video file in your PC and right-click to see [Properties].

2. Select the [Summary] tab and then check the values of 'Video compression', 'Width', 'Height' and 'Frame rate'.

3. Right-click on the My Computer icon on the desktop and select [Properties]. You will see the System Properties window. Check your PC's performance under 'Computer' in the [General] tab.

4. Refer to the following table to see if the CPU performance of your PC can play the video file.
- MPEG1 Video CD, MPEG2 files in Direct transmit mode: Pentium III 800MHz or higher
- MPEG1, MPEG2 transcoding, AVI, WMV, ASF files up to 640x352 24fps: Pentium 4 1.4GHz or higher
