I have created a small project file consisting of
two channels of audio and a number of
Quicktime files with no audio and MJPEG video
streams. Usage of more than one video track, it
seems, crashes the program whenever it
attempts to render or play the composited audio
and video.

Duplication steps:

(1) Clip a portion from a Quicktime MJPEG video
stream; insert into timeline. The clips I used
were transcoded directly from Region 1 DVDs,
and are thus 720x480 @ 29.97 FPS.

Example transcode command line:
transcode -i vts_01_10.vob -o
metro_vts_01_10.mov -Q4 -z -k -q 1 -y mov,null

(2) Add audio tracks (not sure if 2 tracks of audio
are required to duplicate this; but it can't hurt to
reproduce the problem exactly.)

(3) Add a second video track. It can be blank, or
contain another clip.

(4) Attempt to play or render. Cinelerra will
crash.

I'm using the beta2 binaries posted on
heroinewarrior.com (compilation with GCC 3.1
is difficult, and I'm still in the process of
patching.) If this has been fixed in a later
backup, that'd be great.

System configuration: AMD Athlon Thunderbird
850 using VIA KT133 Apollo Pro chipset, NVIDIA
GeForce2 GTS-based video card.
Using Linux kernel 2.4.18-xfs, glibc-2.2.5, gcc
3.1.

    This bug was fixed a long time ago in Cinelerra 1.0.0.
    Just forgot to close the report.
