I am trying to watch some videos, mainly the WP7 tutorials and they are very slow buffering and downloading. Anyone else having these issues?
I wish they would fix this and I am half way through my series and cannot watch the videos.
I tried downloading them but it takes awhile to download and after they are "finished" i play them and its only like half the video.
site responsiveness seems to be back to normal now.
Which series of videos, exactly? For code-on-screen videos, it's best to download the high res versions and watch offline... Sometimes, the high res file is used (at the author's direction) and this causes buffering in our player.
right now - every mp4 I try to download fails. Your feeding me little bits and then the server resets.
I tested many other video sites, they all work now.
open azure up. 47,000 people on line is too much for this set up?
I'm having no luck watching the Silverlight Firestarter videos. I've even tried downloading them in all variations and eventually connection drops. I did a tracert to see what might be happening and visualroute says that theirs 100% packet loss at channel9.msdn.com [126.96.36.199]

So the videos themselves are not hosted on Azure (for any of the examples given above). I do think that our MP4 format may be causing an issue with streaming, but can people test what bitrate they get if they just download the file? When we make an MP4 through Expression Encoder there are a set of 'stream compatibility' choices (iPod, Quicktime or 'Standard'). Since I don't know what people will use it for (it could be for playing in the html 5 player, stream to an iPad, stream to a Mac OSX computer via Silverlight...) I've chosen standard so far. This may not be great for some situations though.
When I try to download a WMV or MP4 file I get a bitrate of 36kb/sec. Which equals like 5+ hours, not good!!! Not only that, it typically craps out after 30 minutes and is not "resumable" from the point at which it craps out; have to start from scratch each time. I have tried to watch the a ton of SL videos on Channel9 and on two PCs they are all choppy, no matter if I use MSIE, Firefox or Safari. They are so choppy and broken up as to be un-watchable. So I try to download them and can't get any further their. When I watch other SL videos on www.silverlight.net website I see none of this same choppy/crapping out behavior.
bump the router, go to CH9 with just one tab open in IE9 beta...
WMV. MP3, MP4 show download numbers like this: 0,6,1,9,83,12,805 kb/sec
navigate to netflix the numbers look like this: 119,121,125,127,128,130 kb/sec
40,000 people on your site
Just came from Silverlight.net where I streamed a whole silverlight video perfectly. Tyed to do that here, the player loads quickly (as do the pages) but the video never plays, just a circle of balls and 00%.
58,000 people on line.
same as above. I did notice that the first part of the video is downlaoding at a good rate but that only lasts for 10 seconds (or so) then it drop off fast, soon I'm only getting a small package of bits every 10 or 15 seconds, after a few more minutes the connection to the server is reset and here I set uninformed.
I've been downloading videos for years without problem but its been going down hill for the last month or so.
Is anyone out there? . . . ....
Only 28,000 online but still the same pattern - slooooooow then server reset.
It isn't my machine (Win7 IE 9 beta) as an xp-IE8 machine on my network has the same problem.
today I downloaded 3 .mp4 show at my optimal rate, then the bottom fell out and I was back to the slow mentioned above.
55000 on line.
Maybe it isn't you or me but somthing in the line between us?
I feel like I'm holding up my end as a customer. CH9 are you listening?
@Mike Greenway: Hey Mike, we are listening, sorry for the delay in responding.
This has nothing to do with the number of people online, or even Azure, we use a massively distributed CDN to host the videos, seperate from the site itself or any of our code...
Having said that, you could probably help us out by doing a tracert to files.ch9.ms to see what the results are. I'm a bit worried that it is something with your provider though, since you are able to download some files from us at a high rate and then you hit slowness.
Just to give you a personal example; every night I watch Netflix and every night it does it's speed test before starting the show and determines that I can only handle the absolute lowest quality stream. Then, somewhere between a minute and 5 minutes into the show, it kicks up to full HD quality and streams the rest of the hour with no trouble at all.
Did my connection suddenly get better? I doubt it. I suspect something with my cable providers network and their attempt to throttle traffic spikes, but I'm just guessing here.
Anyway, send us the tracert and we'll see what we can determine from that information.

So what do you think?
@Mike Greenway:The result might be similar, but the videos are on files.ch9.ms, not file.ch9.ms (which isn't really a site at all, but we have a wildcard mapping on *.ch9.ms, so it does resolve)
If you can paste in that tracert, I'll see if our CDN guys can give us any help troubleshooting your issue. Are you still having problems playing the videos?
