Seems really inconsistent.
Just did some quick testing but without good result.
It never worked for me when it showed the 2 options “Record Episode” and “Record Series/Show”. Analyzation of the recording will fail. Tested with SAT 1 and Pro 7 live TV.
When it didn’t show these options and straight up started recording, when pressing the [REC] button, then the analyzation for download worked (download itself worked as well), when I tested with 2 minutes of RTL. live TV. Also tested with few minutes of ARTE live but that failed again.
I will put some stuff on recording overnight and test again tomorrow or the next days with full episodes of different channels.
