I'm ripping at 720*564 is that going to be a problem?
Still waiting for my Apple TV so I'm unable to find out.

More than likely with MPEG-4. |

From the Apple's own AppleTV webpage:
H.264 and protected H.264 (from iTunes Store): Up to 5 Mbps, Progressive Main Profile (CAVLC) with AAC-LC audio up to 160 Kbps (maximum resolution: 1280 by 720 pixels at 24 fps, 960 by 540 pixels at 30 fps) in .m4v, .mp4 and .mov file formats

Yep, every time. It really helps with the overall video quality and greatly reduces artifacts. Especially in action movies with fast moving scenes. |
I'm just ripping a movie 2hrs 42mins long with 2 pass, AAC audio, 2500 bit rate (apple TV profile) and it's nearly taken 24hrs is this right? |
Using the HB-AppleTV profile with Handbrake, a ripped Pal DVD of 2 hours should take about 3 - 4 hours on a G5 (2x2 GHz) and the same time or less on a Core Duo or Core2 Duo (*). In the average 12 -18 frames are transcoded per second. Both CPUs are working to capacity.
(*) On my MacMini (Core2 Duo 2 GHz upgrade) and 1 GB of RAM the same job is done in within 95 minutes at > 20 fps.  |

I was doing about the same with my Mac mini with 2GB of RAM, but HB 0.9 appears to be giving me a slight boost with the Apple TV setting. Don't hold me to this, but I think my average was in the mid 30's (fps) last night. This was with a "turbo" first pass on a 2-pass encode. |
