InactiveMy user manual says this is a feature of the unit FVP-5000T (on page GB20)
With 3 channels recording selecting a 4th channel and press the record button results a message about conflict and ask which channel to stop recording!
Am i doing something wrong or is the unit faulty

ParticipantYou aren’t doing anything wrong other than not understanding the limitations of having 3 tuners rather than 4 tuners.
All the digital channels from your terrestrial transmitter are grouped onto single UHF multiplexes (abbreviated to MUX). Just one UHF carrier is used for each Mux.
Different transmitters have a different number of Mux. Main power transmitters have an extra two mux (COM 7 and COM
Here’s the details for the Lark Stoke transmitter which I use (To find yours Google Freeview on xxxxx)
https://ukfree.tv/transmitters/tv/Lark_Stoke
If you look at the info it reveals that Lark Stoke has 6 mux
PSB1 – UHF 26
PSB2 – UHF 23
PSB3 (HD) – UHF 30
COM 4 – UHF 23
COM 5 – UHF 36
COM 6 – UHF 48
Here’s the key information – One tuner can record up two channels at once from the same mux. So in the above situation two tuners can record up to 4 channels at the same time from PSB 3 (You can in fact record the 5th by using the time shift buffer.
If you read the info more carefully it says it can record up to 4 at once subject to mux.
So if happen to want to record programmes from 3 different mux you need all 3 tuners so cannot record a 4th. Choose a mux that already has programmes allocated you will be able to record 4.
It’s best to record from the HD mux as 4 out of the 5 HD channels are on the same mux.

ParticipantI should have said instead of –
“So if you happen to want to record programmes from 3 different mux you need all 3 tuners so cannot record a 4th. Choose a mux that already has programmes allocated you will be able to record 4.
Rather this –
“So if you happen to want to record programmes from 3 different mux you need all 3 tuners so cannot record a 4th (unless the Mux the 4th recording is on is a mux you have only one recording scheduled (one of the 3 tuners will be able to record this) .
Perhaps you might like to post an example. of the 4 recordings you want to make.
Often a search for the 4th will find a repeat on a +1 channel or a later repeat on the same channel will find a recording you can make.

I can say that I have not found a 4 channel recording combination I have not found a solution, I do however normally record only-HD.
