  ## Playback Quality

  Files are transmitted to RealPlayer 4.0 in RealAudio or RealVideo format. For optimal video quality and performance your monitor should be set to 16-bit (thousands) or 24-bit (millions).

  Windows Only: By default, the Player produces 16-bit 8 kHz sound. If you hear garbled audio then you can change the kind of sound the RealPlayer program produces. To change the kind of sound produced, select Preferences from the View menu. Select the Advanced tab.

  If you receive poor quality audio, please see our FAQ entry on sound quality by going to http://www.real.com/help.html and selecting FAQ. From there, select Audio Quality.

  Please note that to receive 28.8 Kbps content you should have at least a 19.2 Kbps connection to your Internet Service Provider. Using a 19.2 Kbps connection you may hear slight gaps in the audio.

  Dial-up users should be sure to keep the network connection preference as UDP (the default). In TCP mode, no audio packets are lost, but their arrival may be late enough to cause gapping in the audio. TCP mode is useful when you are directly connected (via a local area network) to the Internet.

  ## Known Problems

  General

  - If your monitor is set to 256 colors, the playback quality may decrease. Use 16-bit (thousands) or 24-bit (millions).

  Macintosh

  - Does not work well with Macintosh TCP. Open Transport 1.1 or higher recommended.
  - If you use Microsoft Internet Explorer make sure that the memory is allocated for at least 5000 Mb and preferrably to 8000 Mb. This will ensure the Mac RealPlayer Plugin has enough memory to run properly. Users of Netscape Navigator may also need to increase the memory allocation.
  - Macintosh RealPlayer installer does not configure Netscape Communicator or AOL. User's will need to manually configure their browser. For more information, see Manually Configuring Your Browser.

  Windows

  - Virus scanning software can cause an error when installing RealPlayer 4.0 . Turn off Virus scanning software prior to installing.
  - Having large applications open may prevent the installer from executing. If this happens, please close all other applications and then install.
  - Starting or quitting large applications while playing clips can cause some brief disruption of the playback.
  - Playback on some 486/25 SX computers does not work properly.
  - The user interface during playback of some high bitrate .8 content on slower systems may have slow response time. Performance of other applications may suffer during playback.

  ## Troubleshooting

  If you experience problems with the RealPlayer 4.0 , please look at the documentation available on our Technical Support web page.

  RealPlayer uses port 7070 for TCP and ports 6970 through 7170 inclusive for UDP transmission. If you are accessing the Internet through a firewall, your firewall administrator will need to authorize these ports. Firewall information is available on our Firewall web page.
