No, unfortunately if a 1080i50Hz program is recorded it will *not* playback on a loit of US HDTVs.
Also the HD-DVD players will not play any 50Hz material even if the region is region1. You cannot get the current Toshiba HD-DVD players to playback anything except NTSC HD, it cannot process any 50Hz material regardless of how it is flagged. It also cannot playback at any refresh rate other than 60Hz, even when all the movies are stored on the disc at effectively 24P, so you get your Judder.
D-Theatre and HD-VHS players will not playback 50Hz material or record it.
Blu-Ray haven't made their mind up yet.
So unfortunately HD is much of the same, 50Hz sped up audio for PAL countries and 60Hz Judder fests with correct audio for the US and Japan.
Interlaced 1080i (not progressive, and can't be made so as the two fields are temporaly different) video for live broadcast material in 50Hz or 60Hz depending on your country. It really is a shambles.
The only place you can do it all is on the PC
