Bug #: 29646
Summary: Microsoft Wine Guide crashes after playing one video
clip
Product: Wine
Version: 1.3.37
Platform: x86-64
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: msvfw32

+mci log
This bug applies to Microsoft Wine Guide 1.0a, a multimedia CD-ROM from 1995.
There are various video clips which should play when the user clicks the
appropriate icon. The clips are AVI files with names ending .CP, e.g.
ACIDITY.CP, ALLABOUT.CP, INTRO.CP. Wine MCI (or msvfw32?) refuses to play them,
since the file extension is not .avi. On Windows the videos play as they
should.
After adding a registry key to associate the .cp extension with AVI files (in
HKLM\Software\Microsoft\Windows NT\CurrentVersion\MCI Extensions), it is
possible to play one video clip. However, after doing that, clicking on any
link causes the program to crash. Navigating between links/pages works fine
before playing a video clip.
The attached +mci log was created (after adding the registry key mentioned
above) like this:
- Start Microsoft Wine Guide
- Click on icon to play introductory video clip
- Click again on the video to stop it playing
- Click "Wine tasting with Oz"
An extract from the log:
