0.2.91 Bugs I Noticed

Interesting bugs... as always.

1. The sound on the Matrix title seems to stay consistently about 1/2 second
off throughout the whole movie. If I pause the playback stream and then hit
play, it is in sync for a little while (maybe 15 seconds?) but then gradually
gets off again.

2. The playback uses almost zero CPU power on my box anymore. This is
impressive! But for some reason it still skips every couple of minutes.
Following a skip, the sound algorithm plays the sound much faster to catch up
to the video. It's really funny to listen to Morpheus, sounding like an
excited little girl, say: "Come on! Stop trying to hit me and hit me!"

3. When playing my L.A. Story title, interestingly, the sound seems to track
very well to the video. It only gets off when the video skips. However, on
this one, the sound is very tinny as though it's going through a bad
resampling algorithm.

4. When in fullscreen mode on the Matrix title, the VLC gets confused about
the aspect ratio, and the picture goes off the left and right sides of the
screen (ie: you don't see the whole picture).

5. After I finished using VLC 0.2.90 (ie: quit the program) my monitor would
blank out then, after 3-4 seconds (independent of keyboard/mouse
activity) come back on. This happens maybe 4 times and eventually quits. At
first I thought my monitor was dying but it was okay until I retested under
0.2.91. This is a wierd one, but I'm pretty sure it's VLC. VLC does not
disable my screensaver during playback, so I guess it's not related to this.

5.1 After I play a short (30-40 second) MPEG stream, my screen will blank for
3 or 4 seconds after playback, then come back with just the VLC control panel
(GTK) at the bottom. This might give clue to bug #5, because the Matrix,
I believe, is coded as about 4 different streams.

6. If I pause the playback for a long time, or play it in slow motion for a
long time, then go back to normal playback, VLC will segfault. One time, it
segfaulted but continued normal playback. Even ctrl-c in the window that
started it wouldn't make it die (although it reported that ctrl-c was
received!). The most bizarre thing. It just kept playing the movie happily.
Finally I had to kill -9 the vlc process.

My system:

 - AMD Athlon 800
 - 384MB RAM
 - Creative 6x PCDVD
 - nvidia TNT2
 - XFree86 4.1.0
 - VLC 0.2.90 before
 - VLC 0.2.91 now
 - DVDs are from United States

Uhm... can't think of anything else. Let me know if you want more info.

Cheers,
