Blurry Video On A DVDR Recording |
|
|
I swapped out an Ilo DVDR05ZU for an Ilo DVDR05MU. I was told by a
CyberHome tech support person that the ZU and MU versions have
different chip sets. The "servo" (laser mechanism) appears to be the
same because the same "front end" firmware is used on both types.
I had previously formatted some Verbatim DVDR +RW discs with the ZU
unit and used one to test the new MU unit. I recorded 5 minute
segments from each of the major broadcast TV stations. I used 4 hour
resolution which worked fine on the ZU unit with a 19" TV set. The
recordings from the MU unit were slightly blurry.
I ran a Nero CD-DVD Speed Scan on the disc and it did not look all
that good. So I did a full erase, wrote the test data on it and reran
the Scan. This time the scan looked perfect - not one defect. I
concludes that it was not the disc but the new MU unit that had
produced a corrupted recording.
I did a full erase on that disc and used the Format feature on the
DVDR. Then I ran the same tests and this time the video quality was as
good as with the ZU unit. I have done several recordings at various
resolutions and they appear similar to the same kind of test with the
old ZU unit.
I tentatively conclude that it is necessary to perform the Format
using the unit that will be used to make the recordings. I suppose the
Format procedure puts down some kind of code that is used by the DVDR
later when it comes time to do the actual recording and that causes
the unit to perform properly.
Comments please.

Why use DVD+RW? At the price of DVD +/-R there seems to be no point.

I thought about that and decided that if I used one disc per night it
would cost me 20 cents per disc (el cheapo 4x at Meritline plus
shipping) and that works out to $73 per year.And that's crap - decent
media costs 1.5 times as much, so the real cost is over $100 per year.
I got 30 Verbatim 4x DVD +RW discs from Sam's Club for a buck apiece
so if all I use is 10 at a time, then the cost is $10.
Do the math.
