Crazy render times on MBP?

I wanted to have a quick look at some footage I shot with my EX-3 and a set of Canon lenses I got hold of.
I put together 1 minute of EX HD 1080 25p footage that I wanted to watch using my WD HDTV box hooked up to my 42" tv.
I need to render the footage to a format the player recognize, so I choose h.264 Quicktime.
I always use the Mac Pro in our editing suite for rendering, but this short ting I just wanted to do on my MBP 2,5ghz.
Itīs been 30 minutes now, and Compressor tells me itīs 1h 10min to go!!
Is this possible?
I have turned frame controls on otherwise left everything as is.

To show a similar workflow I shoot 1920x1080i 25np at 100mbs avc intra on my panasonic 301, it goes into FCP as pro res 422 at the same rates and I can output to pro res 422 at 1920x1080i 25np in virtually real time, I can also output to apple tv h264 at near real time which I then watch on my WD tv box via a memory stick.
I dont use compressor and just go straight QT out of FCP.

Hope this helps pro res seems to be a key here as it is very efficient for output to master and apple tv, I have a 2.16mhz MBP.

Thanks for the reply Gary.
Iīll look into that workflow. I didnīt think of going to PRORES because of space issues on my MBP and I donīt have an external HD here now.
Do you use the log and transfer to go to PRORES?

PS 1h30min left now, oh dear

Update.
First of all, the clip was 8 minutes, not 1 as stated above
I cancelled the job and started over writing it to an external HD instead. The job was done in 40min. This was a portable USB drive as I wanted to play the clip on my WD HDTV. Would probabaly been faster if I used my FW800.

Yes I use log and transfer to go pro res, you really need an ext firewire 800 7200 drive as well but I have done small quick turnaround jobs using the internal esata drive.

I have also gone straight export to USB memory stick to speed up the delivery of an apple tv file to the WD box.

Ok.
I posted this in another thread just now, but here it goes again.
I tried to play back the clip on the WD (8min, 3,5GB H.264, 1920 25p), but the WD choked on the clip. I think it was due to the file size.
A 30 sec version played back just fine

That's an enormous H.264 file for just 8 minutes. What bit rate is the file? For web streaming I am creating 8Mbps H.264 1920/30p files that run to about 50-70MB per minute & they play OK on my WD TV.

I wanted to look closely at the footage I shot so I just converted it to self contained movie to keep as much of the original quality as possible
