I shot video with Panasonic AG-HPX170 in DVCPROHD format which was in PAL. Then, edited by Premiere CS4 and authored by Encore. The final products is a disc image which was burned to a Blu-Ray disc.

Tried to played back by Panasonic BD30 Blu-ray disc player. But the video was down-converted to 576P quality. Is it related to PAL/NTSC problem?

How could I produce a a Blu-Ray disc with Pal contents which is played back by home blu-ray player with HD quality?

I havnt used Encore(use DVD architect), but I doubt it would be any problem creating a 1080/50i BD.

Have you tried play it in your computer and see what have happend.

You didnt by accident downconvert the movie to 576P?

Verified at Encore many many times. Making very sure that Encore encodes the video at 1080i for BluRay.

You cant test the disc with another BD player? Like the PS3.

Isn't PAL a standard definition format, and if it's 1080/50i it's not really PAL? Are you playing back on a US Panasonic player or a European one? Have you checked the output settings of the player, and are you outputting to the TV via HDMI? Is it the player that's saying it's 576p or the TV? Like MovieSwede said, if possible, test the disc in another player too, eg. PS3 and/or your PC.
