First of all, let me say that I can't believe how helpful this forum has been. Waaay better than LG tech support!
I've got a BD390 that has several problems since the latest firmware (Ver. BD.8.08.557.B) was distributed.
First, ever since applying this upgrade, my player refuses to recognize AVCHDs recorded using DVD+R DL media - and these are discs that played fine using 544.B! It now recognizes them as "Blu Ray" and then ejects them. However, my daughter's BD390 works just fine with these discs using 557.B.
After some investigation, I see that my player's "Driver" firmware version is H42301 - and I know from Google that the current version is, at least, H42400 for my player's "older" disc drive. This player was manufactured in May, 2009. My daughter's player (mfg. September 2009) uses H51203 - so it apparently has the new drive... and driver.
When I reinstall the older firmware (544.B), the unit recognizes AVCHD DL media and plays these perfectly - though it does, on occasion, hang briefly and then skip when changing layers.
My second problem is that the player cannot recognize LTH media, while my daughter's player has no trouble whatsoever with the very same discs. In fact, my daughter's player (presumably by virtue of either it's newer drive or "driver" has virtually none of these problems). And this problem does not seem to be related to the player's firmware version. I can only conclude that my problems are due to my having the old "driver" for the player's disc drive.
I spent a few hours trying to locate these driver files (HL04P-ROM) and it appears that all of the megafileupload links are no longer valid.
I'm wondering if there is anyone still reading these forums who might be able to provide, or point me to, the latest H42400 Driver or newer? I love this player's capabilities and if I could just fix this one issue...
