Who needs Blue Ray for skydiving? For about four years I use an IOdata DVD player. It plays HD videos in all formats. One can record up to 10 jumps in m2t format. Plenty heh , one minute per jump. Last year I tested a Helios 3000. Similar to the IOdata but with an additional HDMI output. For no apparent reason this unit was slower and had problems with 1080i (25 MB/s), but worked for slightly compressed m2t files - down to 19 MB/s. Looks like both unit are related in spite of different manufacturers. By accident I used an old remote to control the new unit. Had no problems. Both unit can play, in addition to DVD disks, from memory sticks (USB input), and through internet cable from a computer. Didn't use them frequently. Regular DVD format (720x480) was good enough for two plane jumps.
One cannot record on these units but today every computer has a DVD burner. Capture first and burn a DVD, as a data disk, with m2t or mpg files.
Skydive and have fun,
Andre
