I bought an 1105HC in a pre-Christmas sale and for the most part, it performed flawlessly. I had a pretty large VHS collection taped off cable/satelite and immediately started "mining" any of those titles off my commercial-free chanels and copying them to DVD.
Now, hundreds of DVDs later, it has started burning coasters.
Since I also have an extensive collection of sporting events on VHS, I was looking for an easy way to move them to DVD. So, I decided to replace the problematic 1105HC with a 9016G combo VCR/DVD.
The 1105 continues to work flawlessly with DVD+RW disks, even the well worn crappy Kypermedia ones I got on sale. I use DVD+RW only to transfer video I need to edit from my Dish DVR to my PC, so quality of the +RWs isn't a big issue for me.
But I find the problems with the 1105 to be strange. It appears that finalizing the +R disks is a 100% kiss of death. I can still take a non-finalized +R to my PC and read it most of the time. But all finalized disks are coasters to every software and player I have, even ones that I could read fine UNTIL I put them back in the 1105 to finalize.
That sounded a lot like a software (firmware issue), so I restored the original firmware from the menu but no joy. I then reinstalled the version I had been using since right after purchase; still no improvement. I then installed a new release, just out and still no improvement.
I guess it could be a media issue. I've been using highly rated Verbatim +Rs almost exclusively but the first coaster was the first DVD burned from a new spindle. And the coaster since (maybe 8, I learn fast) are all from that same spindle. However, those same DVDs work perfectly from my PC and none of the DVD coasters from the 1105 have I/O errors.
So it all seems to come back to some kind of software error in the 1105 that happens 100% of the time at finalization and about 50% of the time for non-finalized DVDS but only if they are +Rs.
I don't need the 1105 anymore, but I would like to hand it down to a relative if I could get it working reliably again. But I can't see anything else I can try to fix a firmware problem.
On the other hand, does anyone think it could actually be media (a bad batch)? I'm not inclined to buy more media when I already have a large supply just to see if it fixes a burner I don't need anymore.
Edit: I also gingerly dusted the 1105s guts off through the open tray with some canned air (at a distance to not blow some part out of alignment). Also, no effect.
