Also if you have a camera that shoots DNG (does the K10D support them ?) like the new K20D and K200D you can't use Bibble since they don't support DNG's.
Someone gave me the advise to convert my PEF's to DNG (Lightroom can do this while importing the files) because they claimed the DNG's were a bit better (and smaller).
I'm not expert enough to make a statement on this though (I also never noticed that Bibble was having problems with PEF's but I stopped using it when I got Lightroom).
Oh, and I think when you set Lightroom to import and convert to DNG AND to backup the photo's it will also save the original PEF files in the Backup directory so you have both if you want.
