Version .16 is the best yet! 
The only problem I've noticed so far is that the screen is blanking (due to power management) while the video is playing (at least, it is blanking when playing from the command line).
Tearing would seem to be entirely eliminated - I can't say I noticed a single tear during my testing.
The patched xserver does appear to have a beneficial impact - typically the time taken to output video is reduced by at least 50% when compared with the unpatched xserver.
Excellent work Serge!

How did you benchmark original xserver? Was that done before the upgrade or there's a way to switch between them?

Also it would be good if hafken provided a sample video for audio problem he managed to encounter. Otherwise we have very little chances of getting this particular bug fixed.

Yes, I have Virtual Memory of 128M enabled.
r16 seems to be working fine for me with no issues seen yet.

When running mplayer from the command line with the patched xserver (extra detail - I had sudo'd to root) the screen will blank - my settings are 2 and 5 minutes, LED enabled, Lock screen & keys not checked, default brightness 7 bars. When running mplayer via the GUI app the screen doesn't dim/blank - it's only a problem when using the command line. Nothing special on the command line - just "mplayer -benchmark -quiet <filename>".
Since it appears specific to the patched xserver, it's possibly a bug or issue introduced since the last 3.2007.10-7 release, or a patch build.

The file is too large to attach, but you can grab it from here if you're brave enough to try it!

Apparently it is running mplayer after logging as user and doing 'sudo gainroot' does not let blanking prevention to work properly. Moreover, I just tested mplayer on Nokia 770 and it just crashes in the same circumstances. When just running mplayer as user or root without sudo stuff, everything works properly. The patched xserver is not responsible for this issue. The problem existed in mplayer since the very beginning, but was not noticed before as mplayer is not usually run in such a way (and it should never happen when mplayer is launched from gui). This bug is not very serious and can be easily avoided on normal mplayer use, but I'll try to see what can be done to fix it.
By the way, you can get original unmodified N800 xserver back by downloading and reinstalling it from http://repository.maemo.org/pool/bor...so31_armel.deb
And a warning for Nokia 770 users (forgot to mention it in my announcement post, but this should be quite obvious anyway) - don't try to install this patched xserver on your devices even if you have OS2007 hackers edition, or at least don't blame me if you do (this particular video improvement is N800 hardware specific, so has no chances to be useful on Nokia 770).
