Summary	05647: Multiscreen Games: When using -aviwrite in combination with multiscreen games the resulting AVI file is broken
Description	Multiscreen games like warriorb.zip create a broken video output.
Steps To Reproduce	Launch a multiscreen game with -aviwrite and attempt to view the output
Additional Information	Multiscreen games seem to add a 2 pixel wide screen separator between the screens. Warrior Blade´s resolution is 640x240, but with the 2 pixel screen separator its 642x240. If you force Mame to output the video with -snapsize to 640x480, then the output is NOT broken!

Tried viewing with Windows Media Player got no video but sound ok. After closing Media Player, Windows Explorer malfunctioned and had to be restarted. It was suggested to download Media Player Classic, so i did that (64-bit version). It said 'playing', but nothing happened and the timer did not advance. Lastly, I made an avi of space chaser, and there were no problems playing that back with either player.
