Hi roosmcd!
No, the Download from patches.sgi.com (where supportfolio links) is _very_ fast for me. I've got all five parts fom 6.5.18f within 3 hours, always more than 200kB/sek. This was at my office, on a internet-connection over multiple E3-lines.
"However since upgrading to .17 the software for my Indigo2video won't work anymore... The video base software is not compatible with the irix base"
Have you upgraded the video-drivers with the drivers in the 'unbundled'-directory on CD 3 too?
Cheers,
Michael
