Media on one machine, Info on another

Question

Hi all-
Up until recently, this worked. I don't know if it was an iTunes upgrade, or the iPhone firmware (or neither, or both).
I have my Media (Music, TV Shows, and Movies) and applications on my Mac Pro. My "work stuff" (calendars, mail accounts, contacts) on the MacBook Pro. That is how I want to sync. Up until recently, it worked.
Now, when I plug in to my MBP for the Info items, it keeps checking the other boxes for the media sections, and erases everything on the phone!
I uncheck them all, reload with the Mac Pro, then it does it again.
WHY does the laptop keep re-checking all of those options, and HOW can I get it to stop?
Even when I have the laptop set up to not sync automatically, it still has those boxes checked. If I uncheck them, it still erases the phone.
I have also tried a full restore from the Desktop.
Both machines are on the same version of iTunes (9.0.3) and OSX (10.6.2)

Well, that's what you want on the Summary Pane, nothing checked. The only things that should be checked are contacts & calendars on the Info pane. There should be no checks on any of the other tabs, regarding content. You've already reset sync history, so what I would do is try one more time, connect your phone, make sure there are no checks in any boxes on the Summary Pane, no checks on any of the content panes, check to make sure. Hit apply, when done, if a popup apperas telling you all your itunes content will be erased, click OK. Then go to your other computer, re-sync your itunes content & see if you can go back to your MBP & do just contacts & calendars. This should work, as you can sync contacts & calendars to multiple computers, itunes content to only one.
