I'm using Windows 7 build 7100 x86, the official RC 1. I'm using ShowAnalyzer v1.0.31.680 and DVRMSToolbox v.1.2.1.7.
If I record a show and watch it later, everything works as expected. If however, I record a show and start watching it while it's still recording, it acts as if the addin is not working at all. Commercials are not skipped. Even pressing the right arrow key is not caught by the addin, even though I have the Handle Keys options checked in the settings application. But if I stop the recording, restart watching it, everything works great.
The odd thing that I see while I'm watching it live is numerous events written to the event log by the CommercialSkipAddin that simply say:
