QuickTime FAQ at WebcastingTV:
WebcastingTV tries to keep track of the Questions
and Answers to frequent problems. Most problems are a function of simply
missing one of the steps of a installation or update. Many times an
Internet viewer simply does not realize that they missed something. The
first thing you should always do is retrace the steps that brought you to the
"problem" you are trying to fix.
Another source of frequent trouble is that a
viewer changes something else on their computer, say they install a new software
or hardware, and it interferes with another aspect of their computer.
Please keep tract of the recent events that have occurred within your computer
when trying to diagnose a current problem. Usually the "fix" is
simple, even though the symptoms are confusing.
- Q: When I attempt to play a movie I get only white frames for my video even when I can hear the sound track. What is missing?
A: The most common reason for white video (no video image) is a missing decompressor (the "dec" part of a codec). The typical reason for a codec missing is that the codec used to compress the video is not a standard QuickTime codec; for example, a custom developed codec. If your computer does not have the same codec to decompress the video, QuickTime plays back the parts of the movie it knows about. The installation was not complete, and you should uninstall QuickTime (See Uninstall Questions Below).

Q: How can I view QuickTime 4 streaming content through a corporate network firewall?
A: Firewalls designed to protect corporate information can also prevent you from viewing QuickTime audio or video streams transported using the RTP/RTSP protocol. This is because firewalls are frequently configured to block any data protocols which are not specifically allowed by your firewall administrator (while RTP/RTSP are recognized industry standards, they are rather new).

Q: I get the error message, "PLAY32 caused an invalid page fault". What is wrong?
A: This normally occurs due to a bad download. You will need to download and install QuickTime for Windows again. Be sure to perform an uninstall prior to reinstalling.

Q: How do I uninstall QuickTime 4?
A: Follow the 5 steps below:
1. Open the Control Panels folder.
2. Double click on Add/Remove Programs and the following dialog box appears.
3. Choosing "Uninstall" removes only the applications that were installed by QuickTime 4. Choosing "Uninstall Everything" removes pieces of QuickTime that might be relied on by other programs as well (for example, certain games rely on QuickTime). If you have applications which have a dependency on QuickTime 3 or later, performing an "Uninstall Everything" requires you to reinstall either QuickTime 3 or QuickTime 4 to allow those applications' dependencies to be resolved. An installation of QuickTime 2.x is not be affected by this QuickTime 4 "Uninstall Everything".
4. When it is done, you should get the following.
5. At this point, QuickTime is uninstalled, but QuickTime still shows up in the Add/Remove Programs section. After you have uninstalled it, if you try to uninstall it again, you an error message appears saying that it is already gone.

Q: I get the error message, "Program error. Your program is making an invalid dynamic link library call to a .dll file. Your program will close". What is wrong?
A: The error is caused by having mixed versions of QuickTime on your system. The software gets a response from more than one version of QuickTime--hence the error. Possible Solutions:
a) The easiest solution is to uninstall the program and then do a fresh install. When running the fresh install be sure to say yes when asked if you want to delete all other versions of QuickTime on your system. For Windows 3.x (16 bit) you will need to do a manual uninstall. See Uninstall 3.1 later in this document.
b) Check your SYSTEM.INI file for the line dci=rfmdci. If it is there, comment it out. The comment about dci=rfmdci is a reference to dci services by the video card and has been found to occasionally cause issues.
