As you know MaLa currently will only play videos correctly if they are in a certain format.
It is fussy about the codec. The most common used is the Xvid Codec. Divxx is a NO NO!
Most users never strike an issue but for those who do here is a Video Tester to validate them without the need to load MaLa and set in a layout so you can work out :
1) Does your codec work properly?
2) Is the video set compatible with MaLa?
This application uses the same video engine as mala so you should get the same results.
Bad videos have symptoms such as starting late and/or out of sync with audio or crashing when looped (which is what happens when played on a MaLa layout)
If it proves useful I will extend it's functionality.
Enjoy
