For some reason the DVR (Mac mini) using an HDHomeRun Prime recorded the Indy 500 in SD today. I selected to record the event using the Apple TV guide on channel 232 (HD) and it recorded on channel 4 (SD). I have all the SD channels blocked in the settings for the tuner.
I've never had this happen before. Any idea why? I'd like to prevent this from happening again.
Thanks!
