EDIT: According to a comment from vain below, this is no longer available in the retail version of Windows 7. I have been able to confirm that it does, in fact, still work with Windows 7 Ultimate RTM. Not sure if it works with Home Premium but I would assume that it does.
Wow…if only I would have realized this earlier on. Apparently Microsoft decided to implement a VERY easy way to convert those nasty .wtv files to .dvr-ms files so you can edit and do all the things you used to be able to do prior to TV Pack and Windows 7. I’ve been wanting an easy way to convert some of those .wtv files because I like to edit some shows that I want to keep. So I subscribed to a few threads on The Green Button and received an email yesterday for one of them and user x219c on The Green Button discovered an easy way to do just that. All you have to do is right-click on a .wtv file and you should see a “Convert to .dvr-ms Format” option. Once you click on it, it just make a copy in your Recorded TV folder so you will have both the .wtv file and the .dvr-ms file.
I was also pleasantly surprised that you can run multiple conversions at once without much strain on your PC. In the image below, you can see that I am running three conversions at once and the CPU usage is staying fairly low.
If you’re hoping to convert those copy protected files (such as those recorded via CableCARD tuners), you’ll be out of luck with this utility. I tried to convert a movie that I recorded on Starz and got rejected.
I’m currently using the Windows 7 Release Candidate on all my PCs so I’m not sure if this utility works on any beta version prior to the RC. I hope this helps some others out…I know it’s going to help me to finally be able to edit some of those shows I’ve been saving for a while. Thanks again to x219c on TGB for discovering this simple solution and posting it up.
