Initially we were concerned with the the quicktime render errors that I saw associated with CS5. Ironically none of the described errors I’ve read have given us any problems. I render probably 5-10 different .movs a day across our network. I also have 3 render machines that work across the network. I’m staying clear of 10.5 and hoping the next full version fixes the issues.Knock on wood I suppose. Thanks for your help.
