Canon XTi taking too long to record images

Just bought an XTi in October as a replacement/upgrade from the Original Rebel/300D. I also bought a Sandisk Extreme III 2GB CF card. The write speed of this card is listed at 133x or 20mb/s. When I shoot bands at a night club, I am often waiting up to 5 or 6 seconds for the image to record. Image size set to large. This doesn't seem to be a problem shooting in daylight or ordinary room light. The only time I ever had to wait with the Rebel/300D was if I had shot a burst of 4 or more images, and then it would only take a second or two. I would have the Rebel/300D also set on large, the cards I used in that camera were 80x or 40x. The typical file size with the XTi is about 3.5mb or less and the file size with the Rebel/300d was 2.5mb or less. Could there be something set incorrectly on the camera that is causing long record times?

Thanks,

There is a custom function for noise reduction which doubles the processing/write time, though default setting is off I believe.

My XTi writes miles quicker than old Rebel even with cheap cards & bigger file sizes-takes about 1 to 1.5 seconds for a full 8mb RAW.

Thanks Jonathan! It was turned on.....I don't recall having turned it on though. It did help some in test shots. Things started to slow down after a burst of 3 - 4 shots (which I don't normally have to do) however, a few times it was slow on the first exposure. Problem only seems to be with flash. Last Sunday I was shooting in an auditorium that was fairly brightly lit....I did find the need to use the flash for a few shots and it was definitely a long write time. I will try to shoot some club shots in the next few days to see if having CF # 2 turned off helps. Looking at getting a 266X or 300X card soon as I am also looking at getting a medium format digital set up.

Thanks,

It does record a little bit faster now in low light with flash.....but still way too slow. I'm willing to buy another CF card for comparison but right now it isn't an option. Any other ideas? I just think that it is really strange that it only takes a long time to record low light images with flash....also....the lower the light....the longer it usually takes. I did make absolutely sure that the custom function was turned off.

Thanks,

What format are you saving the photos in? JPEG? RAW? Both? Does your camera exhibit the same problem with either or both formats? Or just in one format, but not the other? Does it exhibit this symptom when you don't use the flash? Could it be that the flash is recharging that's taking the longest time? Or is it really slow writing the file?
