--- Comment #6 from Anastasius Focht  ---
Hello folks,

'iLivid' app/installer mentioned here is abandonware.

https://web.archive.org/web/20131012005744/http://download.cdn.ilivid.com/cd...

The web-boostrapper tries to download the actual installer payload from now
defunct site hence can't be used for reproduce anymore.

Taking the app from bug 33285 ("VideoReDo crashes when saving SECOND file") for
reproducing.

https://web.archive.org/web/20150323155904if_/http://www.videoredo.com/en/Do...

Example video file (mpeg-2):

https://web.archive.org/web/20080604024319/http://users.wfu.edu/yipcw/atg/vi...

Copied instructions from https://bugs.winehq.org/show_bug.cgi?id=33285#c0

--- quote ---
- Loading mpg
- Selecting frames from-to
- Save mpg clip
- Getting a ieframe with stats
This works fine for the first time, but the second time it crashes.

Last line in the log before the crash is urlmon.
After that i get:

###!!! ABORT: Main-thread-only object used off the main thread: file
/build/wine-mozilla-1.9/xpcom/base/nsCycleCollector.cpp, line 1151

'winetricks -q quartz' is needed to work around other insufficiencies. The
reporter didn't bother to mention this.
