Well it's actually more comlicated than this but
I'm using arcsoft total media extreme to make DVD "Blu Ray" discs AVCHD, H.264 discs using 1080i video captured from a sky HD Box (similar discs can be made from component output from a BR or HDDVD player) using a Hauppauge HD PVR.

The discs are encoded as 1080i/25 which play fine on my UK PS3 with the latest firmware but not my US one-also with the latest firmware (it just produces a blank picture).
I am going to retry and burn discs in another format but what will I need to burn to play on both PS3's?
I am not sure whether the HDPVR can capture/produce1080/30 from a 1080i/50 source that I assume the sky HD/BR/HDDVD players will produce from UK discs. But this might be the best bet.
I suspect that similar problems have occurrred from people producing similar discs from HD camcorders.
