The problem still lies with my computer, the fact that it's 3 years old, and its processing power is not sufficient. Once in a blue moon, when the stars are in perfect alignment, my laptop has not been on for a long time, and no other processors are running, I can watch a very long published AVI with the sound never getting out of synch.
On the vast majority of published AVIs, the sound will desynch, and is only fixed if I click on the "place" bar, to realign the movie to a specific spot; the sound will similarly synch to that part, whereupon the sound will desynch again after 5ish minutes. With the encodes I make, the sound synchs perfectly on the short levels; any AVI I make that is longer, the sound will desynch slightly.
Example:
1-01 duration: 11 seconds
4-03 duration: 4 minutes 3 seconds
The 1-01 AVI will almost never have its sound desynch on my computer. If I watch 4-03's AVI in one sitting, at some point after 1-1.5 minutes, the sound will begin to fall behind the audio.
This is because of my laptop's capabilities. For most other people with better computers, you're probably looking at AVIs that don't audio deysynch, but have a file size way larger than needed. Combined, my 52 encodes equals 842 MB, vs. the published .MKV's 210 MB.
Making that audio stream sounds tricky; I don't know what it entails. If you can walk me through it, maybe I can try.
Raiscan, your post made sense, don't worry. I didn't detect any hint of caffeine.
