Usually its the default Windows Media Player that wouldn't play a video file and MPC would play that file just fine...but right now I've a regular .avi file that Windows Media Player would play flawlessly but MPC would play it, but with sound only and NO picture/video?

Video: DivX 5 704x528 29.97fps [Stream 00]
Audio: MPEG Audio Layer 3 48000Hz stereo 128Kbps [Stream 01]

After messing around the MPC's Internal Filters, ONLY after I deselected the AVI from "Source Filters", then that video clip plays in MPC with sound and video , how come?

What are those "Source and Transform filters in MPC" for? and what's the correct or best settings?

Thanks in advance.
