Interested myself if this thing will strip hdr properly, waiting for the report. DIVA will work without issues i guess, but the price.
Okay. So I got it the other day and I don't think it works. But its probably my pi not the device itself (I do not have a pi4 - which has USB3).
Here's the error

Diva is unable to strip Dolby vision for Hyperion purposes
Only lldv from ATV
It is possible could change with software update
Yeeah, I learned that one the hard way.
