Before when I was using Gnome I could edit /etc/Fstab and add the lines //PC1/MyFiles /mnt/PC1 smbfs password=XXX, rw 0 0 and then use Disk Manager to mount manually.

Now I am in KDE and when I added the same line back to Fstab (because I removed it before in Gnome) I get a message like....
/mnt/PC1 can not be found in /etc/fstab or /etc/mtab....
I never had to deal with mtab in gnome...so I looked at it and then added the formated line for my samba shares...but I still get the same error message and I can't mount my shared folders...

I think KDE is far richer then Gnome but I am also discovering that it maybe my far more complicated to learn how to configure properly....I originally thought they were just GUIs looking at the same config files and carrying over regardless of he Desktop, but now I'm not so sure.

Any ideas?

I am not sure I understand FSTAB is FSTAB no matter what window manager you are using. I will have to play with it to see what you are talking about.

Did anybody ever find out what the problem was or a fix for it?

Perhaps you want to read the man of smbmount. and mount manually form a console... or fron gnome (nautilus) use smb:// (in teh address bar).
