After much angst (ticked off), I reloaded FAC.Optibox.RAPTOR.NTSC.v2.10.29.2012Mar26 and it did not restore the CNet file. It maintained the original Airbus file I had uploaded, which still plays fine. I uploaded another mp4 file from CNN and it also plays fine, plus 3 others that did not play. The program is very finicky as to what mp4 files it will play.
The reason CNet disappears is because when you install a NEW file it will over write the current file that is currently highlighted at the bottom of the screen where it shows as <rectangular boxes with names>. The only way around this is to hit the red button and add false info and save. A new rectangular box will appear at the bottom. Highlight that box and then when you insert your USB stick, it will install all the information correctly into that box.
Also, the reason LIVE doesn't work properly is because the URL address you are trying to reach will be checked by that URL server to see if it requires permission to enter that site. In other words, login/password.
Hope this clears up the confusion.
