With family obligations and other time constraits, some developers just don't have the time opportunity to attend developer groups and/or technical conferences. I've found great benefit to attending meetings in person, but am aware that many can't take advantage of these opportunities.
Fortunately, we have been meeting a the OKC Coworking Collaborative that has been video taping our meetings. I personally, find the videos to be of pretty good quality with respect to both sound and video. Below are links to two presentations given by Mike Hotek the 18th SQL Server MVP. Currently, additional videos are available via links on the OKC SQL Server Developers Group website.
