Greetings to all,

MEDION is a German company with a reputation
on the web for well-built, reliable electronic 
merchandise, including a stand-alone consumer 
DVD recorder which retails for $299.

I was extremely happy with my unit, model MD 40570,
which is the only DVD recorder sold by Medion.
I bought 50 Arita (Ritek) brand DVD+R's (it will 
only record on DVD+R) rated 2.4X, and all my blanks
burned perfectly.

Then 2.4X became unavailable, so I upgraded to 100 
Arita brand 4X DVD+R blanks.  After burning maybe 
five of these successfully, the Medion turned every 4X 
thereafter into a useless coaster (and any other 4X
brand I tried, became coasters as well).  This happens 
during Finalization (disc does not truly "Finalize").

(According to Memorex, some internal 2.4X DVD burners 
require an upgrade before they can handle 4X, which 
is a "different standard".)

My questions to the group are these:

1.  Can the Medion handle the "different standard" of "4X"?

2.  Can the wrong media do permanent damage to the Medion?

(Yes, I tried the factory reset, and even the firmware 
upgrade.)

3.  Has anyone seen the seconds counter on the Medion
    go faster, then slower, like mine is doing now 
    intermittently?  This produces a smaller burn area 
    than should rightly appear on the disc.

4.  Could problem #3 be caused by the firmware upgrade?

Any advice would be greatly appreciated.
Sincerely,
the original Tankgirl
