Site Feedback - Videos continually buffer

sokhaty — Wed, 22 Jun 2011 03:11:11 GMT

@Duncanma: Things are looking much better now. For a few days now no buffering and smooth streaming looks smooth again. I'll keep my fingers crossed (though it never really helps )

Site Feedback - Videos continually buffer

What a wonderful rainy day here in NE, have some in-door time to spare. Unfortunately, Ch9 smooth streaming servers do not reply at all (IE9 network capture below). None of the vidoes on the front page would stream.

The funny part is that requests don't even time out. As the result silverlight player hangs and doesn't respond to any buttont clicks. That's one lousy end-user experience...

I wonder if anyone from MS is actually interested in fixing all this mess or at least figuring out what is going on. I'd gladly help by runnung some diagnostics or sending logs somewhere. Just tell me what diag and what logs and where to send them.

Tried to watch Scott Guthrie video, buffering starts after about 4 minutes into the show. There are seem to be some issues with the smooth streaming servers or CDN servers or both.

There is an excerpt from the IE9 network capture (hope someone from MS could look at it and figure out what is causing it):

Yeah, the same experience is here. Constant buffering, skipping and stuttering.Has been happening for a month or so now with approx 1/2 of the new videos posted during this period.

CDN or whatever, could you guys fix it? I'm on Win7 + IE9 + SL4. East cost, Verizon FiOS link 25/15Mbps.

Site Feedback - SmoothStreaming down?

sokhaty — Wed, 27 Apr 2011 02:35:30 GMT

This is very frustrating. Smooth streaming doesn't seem to work for me at all at C9 site and I'm on the East Coast. E.g. trying to watch Yuri Gurevitch's latest video suign IE9 on Win7 Ultimate:

Similar behavior with practically any video on C9 front page. Are you guys asleep, on vacation or someone hacked your servers?

Hint: Requires Left, Right, LEN, and PatIndex You could also write it with Substring if you enjoy pain or are more comfi.

I would accept Print or Select. Really knowing the differences is trivial. Seeing whether you can think through the problem is more interesting.

'You' being sample candidate.

I'm not sure if you changed the criteria, but once you declare the missing variables and load them up, the replacement requires 1 line of code:

Select @NewPath = REPLACE(@OldPath, @OldNode, @NewNode)

Am I missing something?

Definitely you are, try the case with OldPath set to "//4789237/90909/9090901/909092"
and see what happens.
But the point is that the original design is suboptimal (which can be considered flawed).

Gee, a nice sample. But the list of tasks should actually be

* find a flaw in the materialized path persistence design (based on the four lines of code above)
* propose a fix
* write a piece of code to replace node A with node B and reparent node A's children
* and yeah, print whatever the result is
