You are not allowed to play media publicly without the licenses. When you buy music you only have the right to play it for yourself, relatives, friends. Normally the clubs will have the appropriate licenses. Music, karaoke, etc requires a license in order for you to play it legal publicly.

vdjsample file unzipped mp3+g edit ok only video is ok but does not render (unknown filetype 'Invalid return value 0 for stream protocol) because data is missing the one working - with difficulties: record mp3+cdg itself in mp4 (but take care if you enable audio from cdg : level, can't be adjust later) set it as a sample add transparency & chroma key play video and activate sample (at full level otherwhise transparency will apply to video with any audio levels - global, group, sample) you can record full mix mp4 now useless sampler have chromakey & transparency but crashes applying to cdg samples and does enable video chroma & transparency on mp3+g samples but does not render them ^^ because zip is included in. VDJ can natively play karaoke CDGs with the lyrics and record directly in mp4 but initially without background video there are complex ways to acheive this using VDJ only simpler but not full opacity: play video in deck 1 and cdg in deck 2 with additive transition manually set to 50% record as mp4 may need to add chroma and transparency key to cdg which mostly crashes VDJ but will work after that would work but are broken: video editor allows to overlay CDGs over video or video over CDG but have no chroma key & transparency.
