Having to post about all the technical difficulties in this blog is part of the idea of sharing knowledge to people so that if they are encountered with the same issue, they can find the answer through search engines or subscription to this blog.

is not played by the VLC player, and according to a forum post on the official VLC forums, this is a known issue with VLC playing low framerate videos like 5fps, yet the aforementioned video parameters clearly show a 25fps, not something one would consider low in framerate.

As long as it is played by Media Player Classic and VirtualDub, I will ignore the issue. Apparently all I did was screen capture a bunch of BMP files repeatedly, converted them into the AVI container with Xvid as the codec format, and 16 bit depth, 44.1KHz silence audio, appended it to another equally formatted video file and saved the AVI with the direct stream copy option checked for both audio and video.
