Unfortunately, this is not possible. The Blue TV app does not support recording to a USB stick. The content is protected by copyright and can only be used within the app. If you want to watch a programme later, you can use the app's replay or recording function, depending on your subscription. However, direct storage on external devices is not intended.

But does it have the BlueTV app?

Unfortunately, I can't answer that (yet)

I don't have Blue TV, you need a plan to record and the recordings probably stay in the cloud
