Dennis-
I’m floored: you are THE ONLY person I’ve ever heard say they had problems with 4.6…it’s considered by many to be the last truly rock-solid XPro release Avid has kicked out.
XPro HD 5.2.1 is a pretty good release, very solid. A few users have talked about a few hiccups here and there, but I’ve not experienced them. I also haven’t experienced the CPU overload issue on my certified HP xw8000 workstation (dual-Xeon) in forever.
XPro HD 5.2.2 is due out any day. I’ve been told by folks I know at Avid that this will be the last update for XPro 5, because XPro 6 is due in Mar-April (no sooner than NAB will it be announced). With the scary and shaky launch of XPro 5 (horrible software), perhaps 5.2.1 is the version you should upgrade to, then get the free 5.2.2 release when available and hold off on 6 until it’s proven stable?
I know this probably sounds rude, but you might try browsing the Avid forums for a bit more info…there’s lots of great stuff over there that’s being talked about, that’s not being talked about here. No offense to the Cow, you, or the other awesome mods here–and I realize it’s not cool to advertise for another forum, but I’m talking about the official forums from Avid, so I don’t feel too bad. Drop a line over there, they’re nice. The mods are cool, too! 🙂
