Not sure if any app or provider let's you record most do have catch up over 3/4 days
Catch-up Is a service that some providers have, not all of them. And your Firestick doesn’t record entire shows because it’s only 8Go. If you have other apps installed, you can see that the memory gets full pretty quick.
Iptv smarter pro android apk. have screen recorder built in
Use the Cinema app off applinked. You won't need to record any show.
IOS is not the friendliest OS to use with IPTV, Android is the best OS. I prefer Android Boxes for streaming, like BuzzTV, and Formuler devices. These devices allow you to adap storage the right way for recording.
Im using iprotv to record (the channel have to be opened) and to download movies/tv shows, it support catch-up too (only with xtream codes).
There are several ways to record on Tivimate:
purchase an OTG adapter for your Firestick along with a 256gig flash drive name it Tivimate recordings set it as the path to record..
Record to your NAS smb://192.168.0.115/Home/TiviMate/Recordings no issues here at all
Sounds like you could stick with your current provider, but then look into a paid shared plex server for shows you missed.
Ministra maybe?
