No DVB-t2 and MPEG4 are unrelated.
DVB-t2 is modulation
MPEG4 is video codec in MPEG2-TS (transport stream)

Ireland is/will be MPEG4 on DVB-t. UK is first to trial DVB-t2, about q3 
2009 for MPEG4 HD.
The MPEG4 in Ireland is to roughly double the number channels at same 
quality as MPEG2, for Standard Definition. There might be a HD channel 
in the future.

MPEG4 is a separate issue from the resolution used.

There are absolutely no current plans for DVB-t2 in Ireland.

MHEG5 will be used for text and Interactive. It's unknown if the 
extended EPG (one or 2 week  rather than now & next)  will use MHEG5  or 
basic  DVB.  Either  works.  Not all  DTT  receivers and  few PC sw  
does  MHEG5, though  more available than the  MHP  or esp. the misnamed 
"Open TV" used on Sky.
Freesat is an alternative to "Open TV" for Satellite for Program Guide 
etc. It actually uses the same video streams as Sky Digibox. There are 
rumours of PC SW for Freesat EPG soon.
