I have an Asus Rampage Forumula LGA 775 x48 board with an Intel quad core 2.66 Q9400 and 8gb of Kingston Hyper X ram. I am using onboard sound and an Asus GeForece 9500GT 512 vid card. I am using a front mounted USB Hub between the computer and the SL-1 box. I have almost no problems as to performance issues. The 4 processors run at about 60% to peaking at 80% running VSL1.1. Ram useage is anywhere from 2gb upwards towards 4gb at peak. In VSL1.1 video settings, I have the buffer all the way to the right (2gb) and quality at best. In SSL, USB buffer is at 5 (any lower and i get distortion), screen refresh rate is all the way to the right at 60, and my audio cache is set at 60. I am using Vista Home Premium 64 bit, and it was not optimized for SSL/VSL (its my production computer), so there were Firefox tabs open, Vegas and Acid were both open, Audition was open, 3 different messingers, etcetc...

I have been noticing that the output window acts a bit buggy, as to say when I test it on my dual monitors, it goes exactly where it is supposed to go (extended desktop), but when I hook up my projector or output it to my 42 inch LCD (both HDMI in/out), it takes 4 - 6 MANUAL drag/drop attempts before it goes where it is supposed to go (also setup as extended desktop). Sometimes when this happens, the VSL box will turn grey, and I can not see any of VSL on my screen, but the videos still play on extended desktop. When this happens, I am forced to shut down SSL and restart the program.

I also noticed that if you let the mp4(video) keep playing (after the track/video is at the end), it will jump back to the beginning of the video, with no audio, and it seems to be scrolling thru the video 2x as fast. The track pointer is still pointing at the end of the track in the display. This was tested using Absolute mode with Pioneer CDJ 1000mk3's hooked up.

Also on almost all of the Crossfading EFX, I am getting a "green vertical line". Its not always in the same location, and its not every time, but its always vertical.

As I stated before, I am having a minor lag issue on this setup with certain vegas produced video remixes/edits. After some calculations, the video is about 4 - 8 frames behind on these certain video remixes/edits. I tested these same edits with Virtual DJ, and had no issues. I also tested some Promo Only, Rock America and even a "Best Of Bob Marley" Dvd (vob to mp4 conversion using Mediacoder/latest build with Mizu's Serato Profile 2) ripped videos and they seem to be about 1-2 frames behind (but it is not very noticable).

As A Swift stated, I too have noticed the playing deck jump a few frames when loading a new mp4 into the non playing deck. The video jumps, but not the audio. Its minor and happens 9 out of 10 times.

I am using a Pioneer DJM 800 and the M Audio Uno USB to MIDI. I have had zero issues mapping the MIDI. Assigned crossfader and both channel faders, and it worked the very first time, every time.

I will be testing thru-out today, and report anything else that I have not posted in this post.
