My company recently produced a new podcast series called OnMicrosoft (and yes, its about Microsoft). Here's the official blurb.
OnMicrosoft—Each week, we will talk to some of the IT Pro and Developer community's leading experts about a wide range of programming, systems, and software issues. Our interviews include talks with Microsoft’s Program Manager on the .NET Framework- Brad Abrams, Connected Systems Division Architect at Microsoft- Chris Anderson, Wintellect Co-Founder- Jeff Prosise, and Group Product Manager at Microsoft- Brian Goldfarb. With discussions on topics including ASP.NET AJAX, Silverlight, PowerShell WPF, Orcas and SharePoint, we have something for professionals working in every part of the industry.
