Jim, Having problems running quicktime movies. I just bought Peter Gabriel's new CD ROM "EXPLORA 1" and the quicktime display is so slow that the audio keeps cutting out. I believe this is so the video can catch up. I've had same problem with other quicktime movies with sound. Is there a problem with Emplant running animations? I also have Macbench that runs performance test and the video mix doesn't score very good. Does this sound like a problem with my setup? I've tried changing memory settings, caches, and priority setting with no luck. I even tried running the CD in 16 colors with little difference. I have a 4000/040 with NEC triple speed CDROM drive. I use the multiscan driver. CD drive is connected to Emplants SCSI. After NAB I went to Havasu for easter weekend. How do you get anything done in a town like that? Wild – Things going on in this one cove that we don't do here in Idaho. Read message on your BBS and glad to here you are continuing your support for the Amiga. Russ

Russ, You are in DMA contention hell… 82% of the Amiga's CPU is gone whenever chip memory is accessed (like for updating video displays). If you change your screen mode to be something that is not DBLNTSC or productivity, you'll find that the video is twice as fast. Even so, without a video board, you'll find that video will be slower than the audio, so 'skipping' is obvious. Using a Picasso or similar board will solve the problem completely. Yeah, you were here for spring break… it is *the* place. Every major movie star/rock star/etc. was here… what a zoo!
