PVRs: How we test
Recording quality
Lab experts at work testing PVRs
Watching a recording made on a PVR is virtually indistinguishable from watching a live TV show. Unlike a VCR recording, there should be no picture or sound degradation in the recording process. Our lab experts check for this by recording and playing back a variety of different types of programme.
Ease of use
How easy a PVR is to use depends on the quality of its Electronic Programme Guide (EPG). Unfortunately not all EPGs are created equally. Manufacturers decide how this information is displayed on-screen and sadly, some get it badly wrong with EPGs that are hard to navigate and awkward to use.
Timings
We also check carefully that the PVRs don't chop off the beginning and end of recordings, which can be a particularly annoying trait.
Broadcasters don't always stick rigidly to the scheduled timings and it's sensible for a PVR to take this into account by automatically starting to record a few minutes early and finishing a few minutes late. We also check it sensibly overrides this when recording consecutive programmes on different channels so you don't miss the start of the second programme.
The new generation of 'Freeview Playback' PVRs will respond to signals sent by the broadcaster telling them when to stop and start and will automatically adjust their timings for TV shows that start early or overrun.
Ergonomics
Our lab ergonomic experts try out every feature on the PVR making sure it works and operates sensibly.
They generally make sure any PVR we recommend is a product we ourselves would be happy to own and live with.
