Hi brendano

I'm in Kerry - so if you dont mind the help of a Kerryman I can offer some advice
You should be able to connect your hybrid 2 ways, but I'm wondering if you expect to be able to tune sky into your hybrid. Although it's DTT that is not Sky, and the only way to recieve sky is via Analogue via RHF lead or via a phono yellow video lead.
On the back of the Sky box there are 3 RHF sockets. 1 for Aerial in, and 2 for Aerial out TV and a spare one for TV in a different room.
You would need to connect a standard RHF lead from the aerial out 1 or 2 on the back of the sky box into your Hybrid.
Then allow the hybrid / eye TV software to scan, and it should find 1 TV channel.
You will not recieve Sky nativly on the mac with the hybrid, all your receiving is the 1 channel signal via RHF (same as a TV would).
Alternativly if the picture quality is not great via RHF, you can use Composite Phono. However most Sky boxes do not have composite out, so you will have to get a SCART adpater which allows scart output to phono. You can pick them up cheap in somewhere like HarveyNormans for about 5.
Then with the yellow (video) and red and white (audio) cables connect them to the adapter that came with the Hybrid and simply change your EYE TV source to Composite AV1 or whatever its called.
You will still have to change channels etc with the Sky remote and the HYBRID DTT part (Digital Terestrial TV) is absolutely no use in Ireland at the moment as we do not have DTT broadcasting, and by the time the government role it out we will be dead and buried.
Good luck.
