Before the test
Audio, subtitle and EPG language are three separate settings and may come from different sources.
One test result
Use the same screen and programme for one short control run. Record the app version, network path and which feature worked. Keep all account fields private.
Decision record
Write down any terms the provider supplied and which two features are essential. Keep results for the guide, playback and account access in separate columns.
Check language on a single programme
Write down the station and city, then select the track during playback. Repeat on one replay if replay is important to you.
