One of the things I like the most about MPC is the amount of control you get.
Same with VLC.
Some files have video and audio out of sync, and I find MPC capabilities to delay either so they can match quite useful.
VLC does that also in 1 mS increments.
Some other files have incorrect aspect ratio, no problem, I can increase height and width at will.
VLC has aspect ratio adjustment but not infinite. The ratios are fixed at 1:1, 4:3, 16:9, 16:10, 2.21:1, and 5:4. It has interlace / deinterlace, and cropping @ 16:10, 16:9, 1.85:1, 2.21:1, 2.35:1, 2.39:1, 5:3, 4:3, 5:4, 1:1. It has zoom ratios of 1:4, 1:2, 1:1, 2:1.
The extended settings include graphic eQ with presets and spatializer, video image adjust for hue, contrast, brightness, saturation, gamma, you can screw with the color and even invert the colors (whatever good that is), you can rotate the screen 360 degrees, overlays including onscreen messaging and logo.
When projecting to the wall, I like to move the widescreen movies a little down, mpc lets me do that.
Don't know about that. You mean you can interactively move the image up, down, left, right at will?
When projecting my speakers are "reversed", mpc allows me to reassing channels to any speaker, so I don't have to move them.
Don't know if vlc does that, if it does I might give it a shot, but old habits die hard
Most people go with what they know. The best program on the face of the Earth is the one they first learned on. I still know a guy who swears that WordStar is the end-all, be-all. It took me quite some time to migrate to Word from Write.
VLC is pretty cool but I'll look into MPC and see what I think of it now that is has obviously been vastly improved.
