Actually I found, after buying a Canon compact that shoots HD, that even my few-years old Pentium D@3.4Ghz, (video: Radeon 9200) was not able to smoothly play 1080p with common F/OSS players. So I took to shooting 720p, which looks about as good, at least when shot by that not-so-high-end camera, and the files are smaller.

I wonder where the problem was. Nonoptimal codecs? Display? How much does modern 1080p playing rely on the video card smarts?

It is not the 1080p that you should look at but the "Overall bit rate : 12.8 Mbps/s".
Depending on compression, you can have a wide range of bit rates for the same definition, I have an old/cheap camcorder which does 25 Mbps/s at 1080p in its maximum setting (at 60 images/seconds).
Not a lot of PC can play 25 Mbps/s (whatever the OS), even set-top box and MPEG4 hand-held video player have major problems...
