I've been using VDJ on a laptop with a vista operating system for some time, after some initial teething problems I've had a trouble free run. I have just purpose built a PC for my new club with windows 7 Intel R core Duo 2.93Ghz and 4 Gb ram 32 bit operating system. I'm also using a Radeon HD 4350 512mb graphics card with the latest driver updates installed. I have never been able to successfully crash VDJ on my laptop but the new PC is a different story. I've read so many things on the VDJ forum site my head is spinning. Basically it looks like if i run straight off a play list I've made in advance it will run fine, loading the next video in advance and pegging the gain. However if I want to Video Dj dragging and dropping into deck 1 and 2 that is a different story, either it only loads a fraction of the video and the gain is all wrong or it fails to load or the image freezes even though the audio is unaffected. As much as people hated Vista I've not had a problem. I thought I may need to upgrade VDJ 5.2 to solve this problem but it looks like it's a windows 7 problem. Has anyone got a easy fix for this. I'm no computer Guru just a tired Dj that now has his own fixed venue where we are screening videos for up to 10 hours a day. I've just run a play list for around 13 hours seemed to work fine but as soon as I dragged and dropped a video into the vacant deck it jammed up. I think we all know how stressful it is when you have a big crowd and you have a gear failure,I'm trialing all my systems first and are glad I've picked this up now! Maybe it's back to Vista, I hope not!!!!!!
