There were plot holes you could drive a bus through, such as the reason (never explained) why they could only rescue animals moments before animals went extinct - e.g. a few minutes before the dinosaur-killer hit. Why not five years or five centuries earlier? But apart from that it was a fun show, and I prefer it to Primeval.
Anyway, it's available cheaply and the disks, while PAL, are Region 0 - should be playable on most DVD players (not sure about the USA) and computers. It's worth a look if you're a fan of man-dinosaur interaction.
Note - if you look on Youtube for this series you will find several animated episodes - basically, someone has taken the original programs and made animated videos with the show's soundtrack. But the real show mixed live action and CGI, and is much better.
