Hi, I made the final switch to OS X jaguar this automn. After reinstalling everything the firewire port stopped working properly. I experienced a couple of problems with it: 1- Final Cut Pro (or any software) doesn't recognize my Canon XL1 Dv camera. I tried with 2 other DV camera (Canon Elura and Sony VX1000) and nothing worked. Even Apple System Profiler doesn't see the device plugged in the FW port. 2- I have a QPS 16x10x40x external FW cd burner. When I plug it in the FW port, OS X freezes. It does not crash, it just freezes. Everything works well when I unplug (or turn off) the burner. I tried the burner on my friends G4 (running os9) and he no problem whatsoever with it. 3- After those 2 problems occured, I tested my FW port by pluging my Tibook to a desktop G4 with a 6pin FW cable. Holding the T key and everything... nada. Tried to enable a network session throught FW and again nothing worked. I sent my TiBook to Apple Canada repair service and I just got it back after a month and a half... it's like they didn't fixed anything exept the chipped case. The FW port doesn't work. So I restored the orginal OSs with the CD that came with the TiBook and tried everything again.... It still doesn't work. I think to send my tibook again to Apple but I do not want to wait another month and a half. (I need that thing!) Does anybody experienced similar issues with their FW port or with similar devices (QPS burner, DV camera) ? - Francis St-Louis Videographer Montreal (QC) Canada stlouisf at grics.qc.ca PS: I have a second generation Tibook 550mghz. -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
