I have been a serato user since 2004, and video sl since it came out. Both serato and vsl were installed on a macbook 2.2 ghz duo core. In the 2 years playing out at least twice a week, i have never had any issues.

I Just recently bought a new macbook pro 2.2ghz i7 16gb 1333mhz DDR3 with AMD Radeon HD 6750 Graphics card. All my mp3's & mp4's are stored on a 2tb Seagate 7200rpm.

I was stoked to upgrade to the latest versions of serato 2.4.1 and serato video. Until I started having problems. My first issue was with O/S I had to switch from Lion to Snow Leopard. Thinking the problem was solved I tested at home without any issues. Played this past friday with no problem, and then Saturday came. Video kept crashing multiple times. Fortunately Serato did not. I eventually had to disconnect my video feed.

I have removed my old scratch folder, and reloaded all my files. After reload I have noticed alot of corrupted mp4's (according to Serato program) I tested these corruptions in Mixemergency and they play with no issues.

I have now downloaded an older version of serato (2.2) and I am going to use mixemergency. I have been loyal to serato for many years because I have always felt they have been the leaders in digital dj/vj technology. After 2 stressful weeks of vjing, I will use serato for audio and mixemergency for video.
