I am shocked you are having a problem, but, not surprised. I have a T5500 2.27Ghz Quad Core i7 64 bit Workstation with a Adobe recommended Nvidia Quadro Fx3800 video card.> however, we still use Premiere Pro 1.5.1 which is 5 years old and 32 bit bit. However, with CS5 premiere pro you should have no problem, but, if you do, this is how we handle it. Import the H.264 mov files ( must render) which are pretty big into say Premiere Elements either 4/8or the upgraded 9 (which is still 32 bit, but, compatible) in say 10 5sec clips at a time .Export to Movie , trans code ( You can set all this using the Adobe Media Encoder) as Microsoft avi and uncompressed. With a bit of luck the out put file will be cineform avi high definition. Import the avi. 1920 x1080 HD innto Premiere Pro for final edit and Export to Pro Tape or Blu-ray. We are PAL @ 25fps.
Presto the finished project is stunning on a Sony Bravia Full HD 46" Monitor... Incidentally the HD avi clips in Premiere Pro are lighting fast to edit etc.
good luck, and you will have released by now a 5 sec clip of H.264 Mov for say 5 sec or more could be anything from 25Mb to 25 Gb we have often had projects in High Definition taking up to 90Gb or more on the timeline, the old Premiere Pro does not like THAT and may/will grind to a halt. I MIGHT ADD THE NVIDIA QUADRO FX 3800 MOVES THE VIDEO IN THE MONITOR IN NEAR IF/ , NOT REAL TIME. NOT LIKE THE SLOW MOTION IN THE OLD PENTIUM 3.2 gHz hyper-threaded which is recommended by Adobe Spec but, not essential. 800FSB, EVEN THOUGH THE FINAL EXPORTED PRODUCT WAS PERFECT.
Ps In 18 months using the Canon 5D mark II we have finished 25 projects + to tape and 2 to Blu-ray using either H.264 or mpeg - 2 , excellent colour, stereo sound using a Rode Stereo Hi fi Mike.. We also use a Canon HV 20/30/40 as a vtr to Export to tape at Full High definition . 35 min projects take real time, blu-ray takes 52 minutes. Not bad for 32 bit. Your set up should kill it.?
