PROBLEM: THE RECORDING LOCKS UP

Use the patched version of bttv.c at heroine.linuxbox.com/bcast2000.html to defeat most of the bttv lockups. Overwrite the copy of bttv.c in /usr/src/linux/drivers/char and recompile the kernel.

Because there's no way to synchronize them and 4 channel soundcards are already becoming ubiquitous.

Your computer is too slow. Lower the frame rate or compression quality or use a less demanding codec. Another method is to defeat certain operating system features which were designed for web serving. The following script automatically flushes the operating system's cache every second, ensuring more consistant hard drive performance.

#!/bin/sh

while : ; do
	sync
	sleep 1
done

The recording engine uses the Video4Linux 1 driver, which only allows 2 frames of buffering. While an alternative driver, Video4Linux 2 supports unlimited buffering on paper, Video4Linux 2 only supports a tiny number of cards.

Set the aspect ratio in video->resize to what the movie should be viewed in.

Deselect "Disable tracks when no edits" in preferences->playback and select a region on the timeline to play back.

You've got a plugin attached and configured to run impossibly slow. You should save the project, ctrl-C it on the command line, and reconfigure the plugin.

Some file formats like MPEG require previous information to render frames, which isn't available when the file is read backward. Render the movie forward as Quicktime before reversing it.
