This summer I have a production that will use two different units. One will be a 250 and one will be my own 100. I intend to shoot both cameras in 720 30p. My 100 will be used for the playback deck so I want to confirm that content shot on the 250 will play back on the 100. I know that this "should" work, but if anyone could confirm this then that would help in the planning process. If the material isn't playable I'll need to rent a 100/110 instead of the 250. Thanks for the help.

As long as you shoot 720/30 or 720/24 I think you're okay. I don't think 250's 720/60p will play back on a 100/110 but I could be mistaken. I believe that the 250's 720/60p uses a 12 frame GOP while the 250's 720/30 & 24 uses the same 6 frame GOP as the 100/110.
Hopefully someone really in the know will confirm.

All frame rates from the HD-250 will play back from the HD-100 (50 and 60p included). I know this fact from personal experience.
good times...

And someone really in the know has provided the answer. Cool. I stand corrected. That's really interesting to know. Thanks Stephen.

Do you mean for firewire capture? or does the picture actually show up on the LCD?

I wonder how the HD100 can do that, since it shouldn't be able to read the 12-frame GOP signal.

MPEG-2 can have varying GOP sizes as long as they stay within a range of "about" 3 to 18. ATSC uses 15, ProHD uses 6 or 12, HD2 uses 15. It's the Repeat Flags of 24p that can cause a problem on early HDV equipment. I think I remember playing 60p on an HD1.
Sony's new V1 camcorder will even play ProHD tapes via HDMI at 720p60 -- but not 24p tapes.
