Thanks again to IJ, I followed up on his response to me and updated to 2.18 and everything appears to work fine.
TCAS: I appreciate the link that you provided and have bookmarked it for future use. However, it refers to a menu of choices and my interpretation of puma11's request for help is that he wants a simple, no choice recommendation. If so, I would simply update to 2.18.
OTH, if he has trouble interpreting the variations listed in the menu, let me try to help (if I get some wrong, please correct me):
RIPLOCK: NEC FWs put a limit, or lock, on ripping speeds. Some hacked FWs have this removed to enable faster ripping. I use a Toshiba SD-M1712 DVD-ROM to rip, so riplock removal is of no interest to me and 2.18 suits me fine.
RPC: NEC FWs put a limit of 5(?) region changes. Some hacked FWs have this removed to enable unlimited region changes like moving from the USA to Germany and back more than 5 times. I go to UTAH every year without my PC, so region change limitation removal is of no interest to me and 2.18 suits me fine.
Bitsetting/Booktyping: NEC FWs do not allow this feature which makes DVD+Rs readable by older DVD players that can play DVD-ROMS only. Some hacked FWs have this enabled so that burned DVDs appear as DVD-ROMs and are playable by older DVD players. My DVD players are less that two years old and can read my burned DVD+Rs so this is of no interest to me and 2.18 suits me fine.
