OK, I think I got it nailed down. The echoing was cause by (what I thought) table video had audio and there was also a table audio fil playing at the same time so I deleted the table audio and no more echo. The video is another issue, it appears that some of the video files downloaded from GameEx online are encoded with different codex (most likely submitted by different people, some on mac's some on PCs, windows XP, Vista, 7, 8, 10 etc, some with proper codecs and some with who knows what). They are easily spotted by looking at the video file icons, the ones that have thumbnails play nice with PinballX, the ones that do not have thumbnails are the ones PinballX is having issues with (most likely because I do not have the correct codec and a wrong one is attempting to play the file). I removed all the video files that were recorded with an unknown codec and used a static image instead and problem solved. Later I will download the video file again and copy it to my mac and re-encode the m4v to mp4 at a different bit rate, that will most likely work, then add it back to PinabllX (Online unchecked). I hope this helps some people less fortunate like me who know very little about video compression and runs into these problems. But its all fun right?!?!?!
