Hundreds of people with Freeview are complaining after losing some channels when they tried to retune their set-top boxes and TVs.
The service is being upgraded to give more homes channel Five, but 460,000 households are expected to lose access to ITV3 and ITV4 instead.
Maurice Short from Brighton is "very annoyed" because he has lost ITV3 but gained channel Five.

A Freeview spokesperson said viewers with problems should try again.
A statement said: "The majority of people find retuning straightforward but if viewers are experiencing problems after retuning, we would suggest trying again."

There is also a postcode checker available online for people to check what channels they should expect to receive.

Freeview said the helpline was receiving about 200 calls a minute and "most" people were getting through to an agent but if one is not available, then a recording of basic instructions is being played out. Freeview admitted that the website has been crashing because of high demand, but it was working "intermittently".

People with Freeview were advised to retune their TV sets, set-top boxes and digital recorders from lunchtime on Wednesday.

It is thought about 20,000 older set-top boxes will cease to work.
The boxes which will no longer work are: the Daewoo models DS608P and SV900, Labgear DTT100, Triax DVB2000T and Bush IDVCR01.

The technical changes behind the upgrade will eventually enable high-definition (HD) television to be broadcast on Freeview. HD is already available on the free-to-air satellite service Freesat.
"These are significant and necessary changes which will immediately bring Freeview viewers new channels, introduce new homes to existing channels and prepare the platform for the future availability of Freeview HD," said Ilse Howling, managing director of Freeview.

The upgrade affected around 18 million homes, and it is thought that about 25 million televisions and set-top boxes needed retuning.

National re-tune - Wednesday 30 September

On Wednesday 30 September improvements are being made to the Freeview service to pave the way for the digital TV switchover. You will need to re-tune your Freeview TV or box (including BT Vision and Top Up TV) from lunchtime onwards to ensure you continue to receive your available channels, including Channel Five.

The re-tune will allow Channel Five to become as widely available on Freeview as the other terrestrial channels at digital television switchover. Technical preparations for future improvements to the Freeview service (such as Freeview HD) are being made. Freeview will confirm further details about the new service soon.
