Its been in Beta for some time now but RTE have finally launched RTE player http://www.rte.ie/player/
The content is "ok", contains home made shows by RTE and some BBC content such as nature shows and Eastenders, its not great but its a start and a sigh better then what they had.
Quality of the site is reasonable also, not yet as good as BBC iPlayer and it doesn't does not have the same content choice....for example BBC iPlayer has Heroes on offer. [EDIT] I stand corrected I just saw they have Grey's Anatomy on the player
Though in saying all this the service/site is still in beta so I'm pretty hopefully and hope RTE take this change to make some very positive moves regarding on-line content
The site is Geo IP locked so if your not accessing the site via an Irish IP Address then forget about it, (much the same as UK IP with BBC iPlayer site)
For those of you on an ISP with a small cap, its worth remembering that 50min viewing on RTE Player is equal to approx 200MB
