SoftwareSerial on the Arduino Pro Mini 3.3V

I have just spent about a month of my free time trying to figure out why a LinkSprite JPEG camera would not provide useable images for a project I'm working on. The upshot of all my labor is that reading the camera data out of the camera at 38400 baud using SoftwareSerial on an Arduino Pro Mini 3.3V (8MHz) would provide inconsistent results even when I was reading from the same memory location in the camera. When I ran the same software on an Uno (also using softwareserial) the results were error free. Question is, is using the Arduino pro mini for a task like this inadvisable? AM I running up against the limitation of the board? I like the size of the mini but I'm surprised that I'm seeing different results out of the mini and the uno and I'd appreciate any thoughts on what might be going on.

Thanks

I like the size of the mini

Have you tried a 5V model, running at 16MHz?

I have not but I will consider it. Mostly, I'm interested in finding out if anyone else has run into this or am I looking at an isolated problem with this particular chip.

I bought Lilypad with 328 and test it with 485 to realize 38400bauds. It worked for me...
