Description

  1. Game Name and ID (as it appears in right click > properties: "GZ2P01",
    "RSBE01", etc): Batman Begins (GINE69) and Disaster Day of crisis (RDZP01)

2) What is the expected output? What do you see instead?
I expect to see smooth intro-videos like it was before Revision 3d2a2abb49df (r3.0-199), instead I see videos that play at almost half speed (40 fps instead of 60 in Batman Begins) and 15 instead of 25 in Disaster Day of Crysis) and with cutting sound (in a similar way to when you use LLE instead of HLE and get super slow downs)

3) Did the game ever work correctly (i.e. not have this problem) on an
earlier version of dolphin? Please specify the exact revision when the
problem began.
Videos worked perfectly until Revision 7f055d6b568c (3.0-198) included.

4) What steps will reproduce the problem?

  1. Boot the game
  2. Start a new game in the menu
  3. The intro video is very choppy and slow with cutting off audio.

5) What version of dolphin are you using (32bit/64bit along with the
version as it appears in the title bar, etc)?
On what operating system, drivers, and hardware? Be sure to list OS,
graphics driver information, and video card model if you are having
graphics problems, for example.
Revision 3d2a2abb49df (r3.0-199 32-bit) on Windows XP 32-bit, e8400, Ati hd4850

6) Please provide any additional information below.
The problem affects only Jit recompiler, JitIL isn't affected and still plays the videos smoothly and at full speed.
I suspect that some sort of "bug" was introduced in Jit with r3.0-199.
