On a previous post I introduced the feeds I created to subscribe to Mix09 session videos.

I’ve decided to also create a feed for the presentation slides:

MIX09 Session Videos – How I Did It

Paulo Morgado — Mon, 23 Mar 2009 01:04:04 GMT

On my last post I introduced the feeds I created to subscribe to Mix09 session videos.

In case someone is interested on how I did it, here it is:

<%@ WebHandler Language="C#" Class="mix09" %>

using System;
using System.IO;
using System.Web;
using System.Linq;
using System.Xml.Linq;
using System.Net;
using System.Xml;

public class mix09 : IHttpHandler, IHttpAsyncHandler
{
    class WebClientOpenReadAsyncResult : IAsyncResult
    {
        private AsyncCallback callback;

        public WebClientOpenReadAsyncResult()
        {
            this.IsCompleted = true;
            this.CompletedSynchronously = true;
        }

            this.CompletedSynchronously = false;
        }

            get { throw new InvalidOperationException("ASP.NET should not use this property ."); }
        }

        public bool IsCompleted { get; private set; }

        public Stream Stream { get; private set; }

        {
            this.IsCompleted = true;
            this.Stream = e.Result;
            if (this.callback != null)
            {
                this.callback(this);

MIX09 Session Videos

Paulo Morgado — Mon, 23 Mar 2009 00:06:00 GMT

Updated (2009Mar25): Added MP4 feed.

Mix09 is over and I would like to watch some sessions.

I like to watch these kind of videos by subscribing them using the Zune Software as a podcast. I like the Zune Software because it downloads the “episodes” and I can watch them in any order and it never forgets where I was – even if I was watching it in the Zune.

Unfortunately, the only feed available (http://sessions.visitmix.com/RSS) does not include the videos.

Fortunately, the address of the videos is very predictable and I was able to build my own feeds:

The session videos are not available in all formats for every session (at least, not now) but, if you subscribe to all, you’ll get videos for all the sessions.

Subscribe and enjoy.
