I've just spent the best part of 23+ hours re-rendering 2 films.
Both were letterbox format but one was the wrong aspect ratio (it looked stretched).
I set one recode running and started another instance of VD1.10.1-Test11.
I assigned only 2 CPU cores to each instance. SMP multi-processors ('1') set in CPU preferences.
Audio: Full processing mode; AC3 output, 48000, 16-bit stereo.
Video: Preserve empty frames; DivX 6.9.2 in 'Home Theatre' mode.
Video filters: Resize to 692x288. 1 film didn't really need this but I set them both up identically.
Each film was rendering albeit it very slowly - around 1.78fps which I thought was a little strange but left them both to run.
CPU usage (all 4 cores) running at 100% or very close all the time.
When the first of the two completed, I closed the project with CTRL-W and allocated the remaining 2 CPU cores to the other project. This immediately jumped from 1.78fps to nearly 50fps.
Another 30 minutes later that one also finished.
When inspecting the final output, I noticed the first film was only 28MB and MediaInfo reported it as being 3mins 27secs long. I am now having to re-code it again as I write this post.
The second one was fine.
3mins-ish is probably about the right time for me to setup the second instance of VD and fire it off to recode the second film.
So now I'm wondering if multiple-instances of VD running from the same location has some detrimental effect whereby only the last instance actually completes properly.
It's very strange that BOTH VD Status windows looked to be recoding properly - I checked them both every hour or so and nothing in either window gave me cause to suspect that only one of them was actually working.
Anybody got any ideas if this was just a 1-off hiccup or have I found a bug?

Update
Just to add insult to injury, I am now having to recode the second film!
Although the VD output screen looked fine, the actual output was soooo pixellated it was completely unwatchable.
To give you an idea, if you've ever watched a film and you get a corrupted block and the screen looks like its almost frozen and you see nothing but huge great pixels?? That's how the whole film got recoded as - a complete disaster!
