No, unfortunately Sony et al. were too myopic and failed to include an ATSC standard spec in the Bluray spec. HD-DVD did actually include this format which is why it was technically more complete. So you can't deliver 108P30 on BD - but you can *theoretically* broadcast it via ATSC. I haven't checked in several years, but it's probably safe to assume that very few of today's video processing chipsets can properly playback 1080P30 material using correct 2:2 cadence detection. At the time we had this discussion, only HQV's and Achor Bay Tech's chipsets would correctly playback 1080P30 material. but if you were pushing your playback device through an A/V receiver via HDMI, then that receiver would also have to have the same video processing capabilities as the playback device because it sits between the playback device and the display (which is expecting 1080P60 (60Hz) here in the US.
So, essentially, 1080P30 is a defunct format when physical delivery is concerned because proper playback of your production is entirely dependent on the end viewer's equipment which is not exactly reassuring.
Jeff, if you're filming @24P, then you should ABSOLUTELY put out progressive DVDs (content still stored as fields but with the proper flags set by DVD encoder) and 1080P24 BD's.
