Am I the only one that finds silverlight completely unusable? It uses way too much CPU, enough in fact to have the audio go completely out of sync with the video.
For instance I was watching (well trying, but gave up)
this:
Watching it in the windows, gives me about 80-90% CPU usage, but audio already goes out of sync. If I double click to go to fullscreen, than its at 100% all the time and I get like 10-15 fps on the video or something. I tested this on FF and IE7 on Vista 64,
as well as on FF in XP SP2. CPU is an athlon 64 3200+ for the vista system and a sempron 3000+ for xp.
Is there something I can do, or is that just the way it is? Surely that can't be, I can playback 1080i video on the vista machine with less cpu usage 
Please help

If Blackberrys are addictive cellphones, Channel9 is the ultimate addictive website.
Last night I was looking at silverlight stuff and my whole computer bogged down (80- 100%). I had to shut down IE7 and MSN (weirdly enough) before it'd go back to normal.
Don't know if it's the same sortof thing though, since Messenger was also causing problems (apparently). -
I dont think thats the general case. I can see entire video perfectly. When I am seeing the video, my IE process is consuming 33-39 % of CPU (I have P4 Intel Core2 Duo machine with 4 GB RAM.

Well, forgive me if I'm wrong, but 39% on a dual core machine, would equal 78% on the same CPU for a single core. Given that even one of your cores is faster than my whole CPU, you're seeing the same (extremely high) CPU usage.
I don't get why its that demanding. If I watch a video on this site, I get about 50-55% as long as I dont go to fullscreen, than I'm back to 100% and out of sync audio. Watching a video (with I would say the same res/bitrate on youtube gives me between 25 and 30% and about 60% - 70% going fullscreen (which I still think is alot, but at least it works).
Silverlight is completely useless for me as it is..... -

Intel Pentium 4 core 2 duo?
fyi, Core 2 replaces the 'Pentium architecture'.. -

Watched it on a dual core w/ IE 7, had no problem. -

Two things:
I'm sure there's been a thread on this before somewhere.
And is the_Corona anything to do with Corona_Coder? -
I guess it just has high demands then, don't really understand why to be frank, but I really just wanted to know if it could be something on my part.
I'm sure there was a thread about this somewhere else already, but I chose to post here. I'm sorry, I didn't know I wasn't allowed to create threads about microsoft technology.
I don't really see what value your reply brought to this post GoddersUK, but perhaps I misread your reply. I am also sorry my nick somewhat resembles another channel9 member......jeezzz -

On the first point I was telling you so you could find it and see if it had a sollution (fine so maybe I should have linked to it).
And on the second one, I'm sory - I did check your profile afterwards and you're obviously not corona_coder.

Cool, thnx for that link, there is a bit of discussion on cpu usage there, I did indeed miss that thread (well I did see it but I didn't keep checking every reply). Unfortunatly no solution though, oh well...

I get between 4% and 10% CPU usage playing the video on the C9 front page and around 60% CPU usage playing it fulscreen but everything plays smoothly.
I wish gamevideos.com would play that smoothly. It buffers constantly. -
No real CPU issues, just problems with the time taking to render a page where a Silverlight video is embedded.

The real showstopper for me is becomming IE perf and reliability. I'm moving to Opera until at least IE8. And until then, no Silverlight. - And I've been a die-hard IE user for years, never really yielding to alternatives. Some serious investment needs to happen to IE.

Silverlight doesn't use any hardware acceleration that's why your cpu is going high.

I thought something like that was the reason, it's a real pity though as fullscreen just doesn't work for me as it is (and depending on the resolution of the video and/or the size of the embedded video control even that has my cpu sweating.
Is there any work being done to reduce the workload? Or can I somehow get an mms stream (I assume its just that in the background) out of a silverlight page and play that via wmp?
