I don't know with it but with playsound API (from www.allapi.net)
Explanation of parameters:
7 pszSound
A string that specifies the sound to play. If this parameter is NULL, any currently playing waveform sound is stopped. To stop a non-waveform sound, specify SND_PURGE in the fdwSound parameter.
Three flags in fdwSound (SND_ALIAS, SND_FILENAME, and SND_RESOURCE) determine whether the name is interpreted as an alias for a system event, a filename, or a resource identifier. If none of these flags are specified, PlaySound searches the registry or the WIN.INI file for an association with the specified sound name. If an association is found, the sound event is played. If no association is found in the registry, the name is interpreted as a filename.

7 hmod
Handle of the executable file that contains the resource to be loaded. This parameter must be NULL unless SND_RESOURCE is specified in fdwSound.

7 fdwSound
Flags for playing the sound. The following values are defined:
SND_APPLICATION
The sound is played using an application-specific association.
SND_ALIAS
The pszSound parameter is a system-event alias in the registry or the WIN.INI file. Do not use with either SND_FILENAME or SND_RESOURCE.
SND_ALIAS_ID
The pszSound parameter is a predefined sound identifier.
SND_ASYNC
The sound is played asynchronously and PlaySound returns immediately after beginning the sound. To terminate an asynchronously played waveform sound, call PlaySound with pszSound set to NULL.
SND_FILENAME
The pszSound parameter is a filename.
SND_LOOP
The sound plays repeatedly until PlaySound is called again with the pszSound parameter set to NULL. You must also specify the SND_ASYNC flag to indicate an asynchronous sound event.
SND_MEMORY
A sound events file is loaded in RAM. The parameter specified by pszSound must point to an image of a sound in memory.
SND_NODEFAULT
No default sound event is used. If the sound cannot be found, PlaySound returns silently without playing the default sound.
SND_NOSTOP
The specified sound event will yield to another sound event that is already playing. If a sound cannot be played because the resource needed to generate that sound is busy playing another sound, the function immediately returns FALSE without playing the requested sound.
If this flag is not specified, PlaySound attempts to stop the currently playing sound so that the device can be used to play the new sound.
SND_NOWAIT
If the driver is busy, return immediately without playing the sound.
SND_PURGE
Sounds are to be stopped for the calling task. If pszSound is not NULL, all instances of the specified sound are stopped. If pszSound is NULL, all sounds that are playing on behalf of the calling task are stopped.
You must also specify the instance handle to stop SND_RESOURCE events.
SND_RESOURCE
The pszSound parameter is a resource identifier; hmod must identify the instance that contains the resource.
SND_SYNC
Synchronous playback of a sound event. PlaySound returns after the sound event completes.

' code:

I think i figured it out. I can save the resource avi file
to a temporary file on the disk and then play it from
there. But is there a better way to do this?

The best way is not stored in a resource file. That only adds overhead and you always still need a file in hard disk to play.
