PDC10 Video skips

    Hi,

    I recently downloaded several videos of PDC10 sessions.  When I play them, they skip randomly at frequent intervals and it makes them very difficult to listen to and understand.  I have downloaded both high and medium quality, both have the same issue.

    There are a number of posts on the Channel 9 forums about this, some about a month old.

    Are you guys aware of the problem and have any plan to fix it?  I would really like to watch these videos without the distraction.

    I have watched some PDC9 videos without problem.  It seems to be PDC10 encoding that is a problem?

    Hi,

    Can you please supply an example of a PDC10 video that reproduces this problem? We can then test it.

    Thanks!

    OK, Here's an example: http://channel9.msdn.com/Events/PDC/PDC10/FT13 That's the Herb Sutter Lambdas session. I watched it the other day. Both the high quality and medium quality wmv downloads have severe breakup problems throughout. The streaming version produced the same results, and stopped completely about two-thirds through. The download version stopped too, but I was able to get around it by advancing the scrubber to jump over the bad spot. It was hard to listen to, and there are actually short sections of audio that are missing (different in each encoding version).

    @Charles: Yes, I can, though I suspect if you start watching any of the PDC 10 video's, you'll notice the problem.

    The file is: CD01_MarkRussinovich_PDC_Memory_Internals.wmv

    The skipping starts at about the 18-19 second mark, and continues on.

    The MP4 version of this talk is fine. I have submitted a bug about the corrupt WMVs.

    @Charles: Thanks for submitting the bug.  Is there any public tracking of those bugs?  I'd like to know when I can revisit these videos.

    I'm not sure what is needed to actually view the MP4 versions, but I have tried Windows Media Player and Media Player Classic with FFDShow, and VideoLAN player, with no success.

    Still an issue.  Also, still can't manage to get the silverlight player to play anything at all.

    Has this been relegated to the Priority: Low bucket?  I get the feeling that you guys are either skeleton crew, or doing this stuff in spare time, based on time it takes for even forum responses.

    Sorry for the self-entitled attitude, but it's frustrating being offered something and have it not be consumable.

    @Phlow: Yes, unfortunately, this is not a high priority right now. Not sure when it will be fixed.Sorry about that. Please do watch the MP4 versions.

    Same Issue has anyone played the mp4 files successfully? 

    What player are you using Charles? More importantly what codec?

    I tried to use VLAN, KMPlayer, Media Player, Media Player Classic, DIVX Player, Quicktime for Windows, and I have no playback from any of them for MP4 Files.
