HTC although I might be wrong there, it was 4:3 a year or two ago as I emailed Telstra about it and was told that's how it was recorded even though it was obviously 16:9 back then. Had a quick look at the FAQ and it might be 16:9, i guess the quality/streaming just isn't anything great compared to what it could be - makes sense given it's meant to be for phone streaming only. Just wish they'd look at doing their own AFL pass like sports in the states do (probably doesn't because of an agreement with Fox).What device are you viewing it on? I did the trial in pre-season and it was full screen on my Galaxy Note 4 which is 16:9.
