Well, I'm almost done, my internal Seagate 750GB (698.5 FAT32 format) is about full. I've been getting used to fixing some DVD rips with myDVDEdit.
Selecting in myDVDEdits option to play test them in Apple's DVD player lets me know if it works in the Apple DVD player. I mainly use now just Mac the Ripper 2.6.6, and Main Feature Extraction and in preferences check mark the Disable UOPS warning. You can, if the Main Feature Extraction has problems use Title Set Extraction. Sometimes certain studios turn on the RCE, Mac the Ripper says detected and I have to set it to RCE 1 in Mac the Ripper. The DVDs from Dreamworks and Disney (and its subsidiaries) I have to go into myDVDedit, delete the Menu VTS and 2nd command in the VTS cell that states is not found and then it works in Apples DVD player. Overal all for a Mac person, you just need Mac the Ripper 2.6.6 and myDVDedit, and your good to go. That is as long as you like Raw DVD files on your Tvix M-5000U..

Oh and I use Transmit 4.5.x and found that teh FTP problem I was having that it would transfer files over to the Tvix, but the files showed up as 0kb. So In order to get it to work (passive mode on) I have to create the folder first on the Tvix HDD and drag the files inside of the folder into directly to the folder on the Tvix. its probably a mac thing. I hear it happens with FTP.
I just install 1.9.0 beta firmware again and tested a vob trailer playback via ext USB with my iaudio X5 30GB media player. I had it plugged to the Tvix USB host port, had to re-boot the Tvix in order for it to show up on the Tvix menu as a USB drive and played the vob trailer and then played an Raw DVD and it works great.
