    I'm using a moonray indoor aerial (as per watty's post in the "FAQ: ..." post) pointing at maghera with play tv on ps3 connected to a 5 year old panasonic LCD tv.
    How good should my picture look? Clarity detail etc.... Tv3 and 3e are more like lower bitrate channels on sky. There's no blocking or that but is it just a low bit rate or am I picking up noise and should have a DVD quality picture, if I had a better set up. Rte's are better but news now is only as good as the web version.

    Sounds about right, those are fairly low bitrate, and 544x576 I think.

    Should be about the same bitrate as the other SD channels and the same resolution. Could be down to the original video quality of the material being transmitted.

    I wasn't happy with the picture quality on the Play TV to be honest - RTE2 was fine, but all the other channels looked like they were made up of giant pixels (almost like a mozaic).

    Saorview on the same TV using the built-in tuner was considerably better.

    Csi new York looked pretty good last night. That should be hd quality to start with then probably down scaled for rte's sd needs.
    I did get the blocking effect when changing channels initially but then they'd play ok. That's probably the live buffer gearing up on play tv though.
    Still reckon tv3 and 3e were below sky standard transmissions for the same channels.

    Play tv doesn't give strength and quality figures, as far as I can tell, so does noise manifest itself the same as say in a digitial photo, higher ISO giving a picture more fuzziness?

    In short No. You won't get noise in a digital signal, when the signal gets too weak the picture quality just falls off a cliff. You'll get major blocking and freezing.

    The issue you are describing is probably to do with the quality of the picture being broadcast perhaps in combination with the quality of the tuner in Play TV. Some equipment will scale and clean up the picture before display better than others.
