It can be handy to create custom RSS feeds for the Zune so that it is easy to download and watch selected videos. You can watch these videos either on your PC, or on the Zune itself. Here is a custom feed I created that contains all the new C# 4.0 language and IDE How Do I Videos, plus a selection of other How Do I videos. In total, at this time, there are 35 videos in the feed. The RSS I created uses a simple and quite minimal syntax tested only with Internet Explorer 8 and the software for Zune 4.0.740.0. The source for the C# program that generated the feed includes regular expressions, LINQ to Objects and LINQ to SQL. I discuss that program briefly at the bottom of this post.
