The internal frame rate limiter does not affect the frame rate or speed of the resulting video. It might however have an effect on texture/scenery loading, can't tell for sure, would be interesting if some users could experiment with that. Possibly it could also slow down the rendering process slightly when set lower than the video frame rate.
I don't know how that external frame rate limiter works, but would expect the same here. At least it shouldn't have an effect on the resulting video's frame rate/speed.
2. The frames setting in the renderer -- does that have any affect on the rendering or is it designed just for purposes of the playback of the wmv. I guess what I'm getting at is it defaults at 25 but in the US should we use 30 or 24 based on typical frames on NTSC display, or doesn't that matter?
It is the frame rate of the resulting video, and therefore also affects the rendering; if you enter a higher frame rate, more frames have to be rendered, so rendering will take longer.
You should choose the frame rate depending on how you want to play the video. For playback on a PC monitor (which usually runs at 60Hz refresh rate today) 30 or 60 fps is a good choice to have it synchronized with the monitor frequency. If you want to make a DVD choose 25 fps for PAL, 29.97 or 30 for NTSC.
3. I experimented with capturing sound using audacity. Is there some way to create a sound that could be used for an external camera for synchronization? For internal cams I guess a switch click would work but haven't figured out a way to create a sound that you could see in the video and hear in the audio.
I used pause markers to synchronize recorded sound with the rendered video. When FS is paused there's no sound output, and the silent parts are easy to identify in the recorded audio.
