New Post: Created WTV files won't play in WMC

I'm a long time WMC user, but trying MCEBuddy for the first time today. Running Windows 7 64 bit and MCE 2.3.13. When using the WTV Unprocessed profile, the created files won't play, WMC says "Decoder Error"
I found this issue in the wiki, it said uninstall upate KB2670838. That update is not installed.
They will play, with some issues, if converted to .dvr-ms, but that's not a long term solution.
