File size/bit rate of dvcpro 1080 60i vs dvcpro 720p?

Recently, I took some HDcam footage in (transfered from 35mm film) to get transfered to DVCpro HD 1080 60i so that I could edit it on my own system (FCP). The first time they made a 720 p copy instead so I had to take it back it to get redone to my specs (dvcpro 1080 60i). Curiously when I brought my hard drive home with the new dvcpro1080 60i footage, the overall file size (approx. 20 min. of footage) was the same as the 720 copy they had mistakenly made earlier (22.6 G). I fully expected a larger file size as the data rate would be higher. Am I missing something here? Do you think that they simply uprezed the 720p version? or?

well have you opened it in fcp?

It could very well be that the data rate of either is the same so it can run over firewire.

The data rate on DVCPro HD is 100Mbps, regardless of whether it's 1080 or 720.

does that mean that 720p, dvcproHD is less compressed, therefore having higher quality than 1080?

Yes, but the obvious trade-off is resolution. Which means that when viewed on a 40"or bigger monitor, both formats will look identical.
