Good on yer!
Check the FAQ's (page one, post 7?) and ensure that you follow the FW update procedure to the letter. And punctuation!! In these almost 1 thousand pages, are far too many tales of woe brought upon the innnocent by a botched FW update.
Absolutely, good fortune to you.
p.s. Just for giggles I called Pioneer Customer svc today, parts order, and got an update (1.71 now) on it's way. Took about 8 min with hold times and chatting-up the nice lady on the telephone. I'll install if I ever need it.
p.p.s Rick R, above a few posts, and many others have outlined some simple cleaning steps for our problem children. The Pioneers I mean. Careful cleaning can have some wonderful effects on these units. Even a good brush disc can help (see above). Just as dirty environments and disks can ruin our whole movie night at home.
