Ch. 7 RTENL has now been renamed RTÉ Two Temp.

The epg entry reads:

This is a temporary service which will cease in early 2011, viewers unable to receive RTÉ Two pictures on EPG channel 2 are using a TV or Set Top Box (STB) which is not compatible with the Irish DTT platform – Saorview

Or it may read:

This temporary service will cease 18 April 2011, viewers unable to receive RTÉ Two pictures on EPG channel 2 are using a TV or Set Top Box (STB) which is not compatible with the Irish DTT platform – Saorview
:RTÉNL endorse only Saorview approved equipment. Approved TV or STB will display RTÉ Two on EPG ch 2, viewers unable to view RTÉ Two pictures on EPG ch 2 need to replace their current DTT equipment and should contact the equipment supplier

No doubt this is to make the point to eBay sellers, early adopters and unscrupulous Irish dealers selling MPEG4 set-box that has no HD (or Dealers selling any CAM adaptor). These will not work on Saorview. See the Black List

If yor set-box or TV has only MPEG2 and not MPEG4 you will only get the radio stations. Possibly TV sound on some models.
