Batch Process tiffs to jpg

Hi,

I'm trying to batch process about 1500 16 bit tiffs to 8 bit jpgs. I record a new action: open the file, convert the bit mode to 8, save as a jpg in a different folder and then close.

However, when I run the batch it saves the first image as a jpg and the rest as 16bit tiffs, basically just creating a copy in the new folder. I tried using PS 7 and PS CS3, on both a Mac and PC. Same thing always happens.

I'm not sure what I could be doing wrong... any ideas?

Thanks,

Thad
