Known Problems

General

• If your monitor is set to 256 colors, the playback quality may not be optimal. Use 16-bit (thousands) or 24-bit (millions).

Windows

• 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.
• Windows 3.1 users need to have Video For Windows 1.1e installed for video playback. RealPlayer searches for Video For Windows during installation. If it is not found, you may download the Video For Windows package from our web site. This link is on our RealPlayer download page.
• Windows 3.1 users with older video cards may experience video playback problems in 256 color mode. Incompatibilities have been observed with the PGP.DRV for the STB Powergraph series. Downloading a new Powergraph driver will usually fix the problem.
• Windows 3.1 users using only a 256 color display may not be able to playback video using the Netscape plug-in. Downloading a new video driver may fix the problem.

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, but 8000 Mb is recommended. 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.

Unix (For more information, look at the README.FIRST file installed with RealPlayer).

• The home button will not launch your browser if it is closed. If your browser is open, the home button will send it to the RealPlayer home page.
• The RealPlayer may not be able to allocate colors in the color map when there are many other desktop applications using a large amount of colors. This results in random colors in the video. The workaround is to exit other applications that are consuming display colors.
• The zoom feature in the Player's view menu is not enabled when RealPlayer is run on 8-bit displays.

Troubleshooting

If you experience problems with RealPlayer 5.0, please look at the documentation available on our Technical Support web pages.

Using RealPlayer through a Firewall

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.

Full Screen

• Microsoft DirectX Tools with DirectDraw: download from Microsoft. When you install DirectX, you must choose to upgrade your video drivers. However, you may lose functionality of your old drivers.
• Updated video drivers: get these from the company that manufactured your video card or from RealNetworks' Full Screen support pages. If you update your drivers, you may lose functionality of your old drivers.
