I've been using vegas quite blindly to produce short clips (the content) and short 1 minute loops for the menu backgrounds in DVD Architect, but until now, I never really realized how CPU hungry my DVDs were - 20-80% CPU usage in PowerDVD on a 2GHz laptop while just sitting in a menu loop. If I monkey around with anything on the laptop, the DVD will stutter - that's how bad it is. When I look at the numbers for a commercial DVD, however, it runs steady at about 50%. Interestingly, if I play (with PowerDVD) the DVD from the hard drive on the development machine, the numbers are less than 25%. My DVDs play fine on a set top player, so that's good, but this software thing sort of bugs me. I guess my question is: Am I doing something wrong by choosing the default parameters for Vegas and DVD Architect? If so, what're the best settings to produce a decent DVD that won't bring your average laptop (1.5GHz and the like) to a crawl? Thanks in advance.
