Innuendo: by "additional problems", I meant with the service, not people's computers. Easy fixable should perhaps be "easy to workaround", just increase the rate interrupts are being throttled at (I wouldn't be surprised if there's already a hidden registry entry to control this). Yes, would be better only to do the throttling if it's necessary (measure if video isn't decoded fast enough), but it's a nice feature to actually have.
You keep mentioning this is a good idea for HD video content. While I agree, why does this thing kick in when someone plays an MP3...a task that takes up 0.02% CPU load on a modern system?
-Innuendo
Because the thing wasn't designed well enough (seems to be a reocurring event with Vista), and probably because the designers didn't think people running fileservers would use the fileserver for media playback

(with normal framesize, it really shouldn't kick in unless you're on a >100mbit connection, so there's "something wrong" either with people's frame size or the ndis code handling throttling).
why am I able to download HD video trailers from the internet, play them, and my network speed isn't affected at all?
-Innuendo
Well, try full 768p or (ouch!) 1080p H.264 playback... that's a bit different from the normal HD trailers, especially if it's a full-quality codec being used... apperantly the commercial (and fast!) CoreAVC codec does some tricks that speeds up stuff massively, but reduces quality somewhat.
No, while there's a lot right with Vista, there's a lot wrong with it, too, and the complaints about it on the internet go beyond the usual complaints that are common when MS releases a new OS.
-Innuendo
I fail to see much of what's right with Vista, to be honest

- I'd love to have some of the kernel
improvements, but all the extra crap they added... well...
