"AFAIK, no one has worn out a DVD drive in a Philips 357x or Mag 2080/2160."
Okay. That makes me feel a bit better.

"E9 is an error indicating some special data is missing... "NV_PCK/RDI_PCK is not in encoded data" whatever that means."
I'd occasionally also get an "E 22" error message, which I believe is another disc (DVD) reading error. Or, at least, I think I read that somewhere online. Maybe (hopefully) it was indeed just a few bad DVDs. I've never come across three bad ones in a row before though. (I think I've had it happen maybe *twice* before in the entire year plus that I've been using the DVR, and one of those times I later figured out it wasn't the disc at all but the thing about not being able to finalize with less than an hour before a timed program beginning.)
"Do you use 16X discs exclusively, or do you have some slower-speed discs you can try, even if RW?"
I'm at work so I can't check which kind of discs that I've been using. Just the standard DVD-R, I think. I can't remember the speed, but I presume 16X like you say. I buy them usually in the 50 or 100 spindle packs and, like I said, have never really had any problems with them. I dub everything to them at SP (high speed dub) and the picture quality is fine (a bit less so on the stuff that I'm transferring from VHS, of course). All I have is the most recent 100 pack that I bought. I'd recently run out and gone out and bought a new pack. (I don't think that I have any RW DVDs.)
"JFTHOI< you could check your machine's DVD usage data:
Press SKIP 321 buttons on remote (all within 3 sec), which brings up a screen with DVD-WR/-RD times (hrs:min). Exit with Back button."
Okay. Thanks. I'll try that some time.
I left the machine dubbing to another disc when I left for work this morning. Hopefully I won't have any problems editing and finalizing the disc when I get back home tonight.
