           Summary: MCM2: wineqtdecoder crashes after intro

        OS/Version: Mac OS X 10.5

          Priority: P2

console output including crash backtrace

Motocross Madness 2 (MCM2) crashes at the end of the intro video (ran to
completion or aborted with a key press), prior to entering the main menu.
According to the backtrace, wineqtdecoder is involved:

=>0 0x92106354 CFRelease+0x24() in corefoundation (0x0032ec58)
  1 0x45df93a9 _QT_Release+0x118() in wineqtdecoder (0x0032ecb8)

yet I'm wondering what role it's playing, because MCM2's Intel Indeo video has
been playing fine in Wine long before wineqtdecoder was added. Disabling
wineqtdecoder.dll gets past the crash with no observable loss in functionality.

The backtrace is attached. I once had another backtrace involving
QTInPin_Release in wineqtdecoder, also at the end.

Native amstream, quartz and devenum are needed because of e.g. bug #17836.

Perhaps the crash is caused by missing functionality in the new decoder,

The demo is presumably not affected, because it does not play a video.

BTW, there's some regression between 1.3.17-282-g3ec195 and 1.3.18-244-g34ba20
that causes MCM2 to receive no mouse clicks in the main menu => dead => garbage
rating.

What component would suit this bug? still quartz?
