Yes came across it the other day, runs everything mpc-hc does. As Sammy says its a fork of mpc-hc. Quite stable for a 'beta' - resolves my issues with chapter skip. Unless under the hood is different, there is little to distinguish the two - slighlty different OSD, but presented along very similar lines to mpc-hc
Sammy - its almost identical - one or two cosmetic changes, but that's all - certainly that I can see. I can use it the same way I did mpc-hc, with the exception that chapter skip works with this build.
Sorry yes to answer your question - right click menu system as before.
When you guys say "chapter support in mpc missing (or not)", last time I played a DVD I could skip chapters back and forth. Same goes for chapters in mkvs (if those are included). So I don't think that that is missing (not working) in mpc-hc. Could well be a configuration issue due to keys being mapped to other functions.
Chapter skip is there in mpc-hc and all variants, but has been broken for at least the last 2 builds - misses chapters on skip (ie moving from 1 to 3, 4 to 6 etc) have raised this as a bug with the devs.
