I've seen it said here and there that "getting a firmware update CD from Panasonic takes forever".
I received three "presents" today.

The two ethernet cables that I ordered were delivered (one 7 foot, one 50 foot)...
...and the Panasonic firmware update CD arrived in the mail (apparantly with 1.7 ; the label is stamped "Panasonic / Customer Call Center / Ideas for Life", "FWV17BD60", "DMPBD60"). I first ordered the CD from the Panasonic USA website / support, last friday via email. Thats only SIX DAYS, from the time that I ordered it, until I had it in my possession.

I checked the Image Burn forum - no response to my offer of holding off.
The author of imageburn "kind of" implied that he would work on this (now that he had clues, apparantly he downloaded and burned BOTH 1.5 and 1.7 using * WinXP *, and compared that to an Image Burn burn (that sounds funny. BurnBurn)), a day or two ago (two days, depending on your viewpoint), said that " .. by the time he had it finished and ready to test it on someone, my problems would probably be sorted out".
I know that he has logged on several times after I responded with an offer to WAIT on upgrading the firmware. I realize that for him and the rest of the ImgBurn community (on THAT forum) that this is a low priority thing... about 4 years of Image Burn, and I think I am the only one that has posted in the * ImgBurn * forums on this.
No problem. I posted (a positive post) that I was going to go ahead and upgrade, but I asked him to please be aware that owners of a certain Blu-ray player (and probably other models) would be appreciative if the Img Burn problem was fixed.
Coffee. At least two cups.
Then I will upgrade.
(edit)
Upgraded from 1.1 to 1.7, courtesy of the CD mailed to me by Panasonic. I loaded movie 2 from the ONE Blu-ray title in my collection (so far, next to my mountain of DVDs), "The Pirates of the Caribbean Trilogy". I played the "Liar's Dice" game with the scallywags - I imagine that is loaded with BD-Java, and if anything could make the firmware cough..... everything is working perfectly. I always lose the game - those mangy motherless dogs! Avast!
