Maybe I'm spoiled from owning a couple of Toshiba RDXS series recorders. rolleyes.gif

Using my Magnavox MDR 537H
"High Speed" Dubbing about 90 minutes of SP recorded content, all 1 title on the HDD, over to a Sony DVD-R 16x takes about 25 minutes. Is that about what others are seeing too? Am I missing something? Should I be using different blanks?confused.gif

Thanks biggrin.gif

That's too long. Previous model (515) will do 2 hours of SP in 16 min. or less on 16X disc. Not sure what to tell you, except try an 8X disc if you have any and see if any diff.?

It's even a bit of a slowpoke loading a blank DVD but the Tosh's were too. Did I read somewhere that some of the 537's were made using smaller laptop DVD drives? Could those be slower drives? I got this 537 in July from W*llm*rt and the serial number tag says November 2012.

That mfg date might or might not be about when they changed to 2-1/2" drives after discovering a problem in October (or thereabouts). I don't think the physical size of HDD drive could make a speed diff. on DVD dubbing?

 

You might also try a Verbatim Data Life Plus AZO disc, prob. the best available today. I'd got for 8X.

Are 8x DVD's better to use for the MAG? Any preference for "+" or "-" ?

+ or -, whichever you can find best, prob. online. +R is technically better, as described here... prepare for a brouhaha now! :)

I've never used plus. I don't recall why now. Since the Mag is essentially a Phillips product, maybe going plus is a good idea. I'm a long way from needing new blanks but the next time I'll try some 8x+ if I can find them and see if that helps.

The resulting DVD burns seem to play fine on my other players, even an old JVC that's very fussy. I don't know if I could get away with trying to exchange this 537 at W*lm*rt altho it's not 90 days yet. I like the machine, would only want another of same.

Any other Mag 537 owners noticed time to "high Speed"dub about 90-120minutes of SP content on the HDD over to DVD?
On a hunch I picked up some Sony DVD R+ blanks since previously I've only used minus. Made no difference. High speed dubbing time for about 2 hours of SP content takes 25 minutes.

Any more feedback appreciated.

I'm thinkin about sending the Mag in for an exchange.

Yes, we need other 53x users to report their HSD times, including show run time, disc brand and speed.

 

I don't think anyone else has so far reported a difference from the times in my chart in the HSD help file which we've been assuming is the same as the 2160A and 515 times in the chart.

That is the kind of burn speed expected for a 2X burner.
A 1X speed burns a full disk in 1 hr; 2X = 30 min; 4X = 15 min -- that's simply the definition.
2 hr of SP content is nearly a full disk.

As was noted, you need more data from other users burning full disks with various media to see if this is an aberration or normal for these units.

Not true for High-speed dub (HSD). The older Mags with 4X burners HSD'd a 2-hr SP program in ~34 min. vs the 25 min. the OP is seeing.

 

Mag units from 2160 on had 8X burners, with ~16-min HSD times for 2-hrs of SP.. Still unknown if they carried this thru to the 53x Series.

What's not true?
If the older units were burning a full disk in ~30 min they were burning at 2X speed regardless of what their burners were rated at.

Same goes for the newer units. If they were burning a full disk in ~15 min then they were burning at 4X regardless of what their burners were rated at.

That's a simple definition of the terms. 1X = burn a full disk in ~1 hr, and so on.

Just requesting a point of information here. From reading the replies.

Is the actual amount of recorded time from the source irrelevant? Dubbing time in the "high Speed" mode is strictly determined by the amount of data from the source being transferred?
In other words,
4.7 gigs of data on the HDD will take the same amount of time to High Speed dub whether it's made up of 2 hours of SP or 6 hours of SLP.?
Is this right?
Somehow I thought differently. But that makes sense, data is data.

Yes, you have it right. It is based on the amount of data and not the recording time.

Of course, in order to HSD a title, you have to burn it in the same video mode it was recorded in (i.e. SP). If you change modes it has to recode the video on the fly which happens in real time and limits your burn speed to 1X or less.

OK that's a little ambiguous.
In the Magnavox dub menu, No bitrate/speed option is available for "High Speed" dubbing. I assume in HSD, whatever speed/bitrate mode the source is, the dub to DVD will be done in that mode too. No recoding of the source is needed and thus the dubbing takes less time. It's just a simple transfer of data to the DVD.
The other modes available, dubbing in SP, LP, SLP , etc., are for when you want the dubbed data to play at a different bitrate from the source. For instance you want to fit 4 hours of SP recorded content on 1 DVD. You would have to lower the bitrate of the source data before transfer to get it on 1 DVD. It has to be recoded and that recoding would likely make the dubbing process much slower. right?

Well I'm gonna find out the answer. At least if all goes according to plan.
Thanks to W*lm*rt's liberal 90 day return policy. As I understand it, they are going to send me another 537 even before I send back the one I have. So I'll get the chance to compare 1 for 1 and see if the second one does HSD to DVD's any faster. Watch this space for the exciting conclusion!

In the past hour I also got caught up on another show.

Set-up was different.More shows less quality.

Going from SPP mode to LP
The DVD Recorder needs the same changes done manually.
So I pressed the dvd button and almost forgot to press the REC MODE button
at the bottom of the remote.
It was set on SPP not LP.
It will record.
But it will take ALOT longer!!

I set the DVD speed to LP.
Result High Speed mode.

Thanks for the info. Since it was recorded to the HDD at SPP I would expect less High Speed dubbing time than if it had been recorded in SP. So it's interesting but doesn't really reveal much in comparing to SP recordings.

(3 Days of the Condor-great movie BTW. Even the dated espionage technology remains fascinating. Redford and Dunaway are excellent but Max Von Sydow steals every scene he's in)

Well I give up. frown.gif
Received the second MAG 537 in accordance with W*lm*rt's 90 day exchange policy.
Recorded 1hr 45 minutes of content to the HDD in SP mode.
High Speed dubbing that title to a Sony DVD+R 16x
on the second MAG 537 took the same 25 minutes.
That's exactly how long the first one takes to HSD that amount.
I don't know how you guys are getting 16 minute HSDubs on your older MAG recorders.

I'd like to hear from other owners of specifically the model 537.
How long does your Mag 537 take to High Speed Dub about 2 hours of SP content to DVD?

As for this second "newer" recorder. The Manufacturing date is September 2012.
The first one I got is November 2012
so the replacement they sent me is actually older.
I think I'm gonna send back the second one! eek.gif

Well

I did a couple of test's @ SP on my 535.
BTW the 533-535-537 models are virtually the same.
The Hard Drives are the difference.

My tests

Test 1
Length 2:01:59
Start 11:12 pm
Writing to disc 11:40
Time 29 min.

Test 2
Length 1:57:20
Start 11:47 pm
writing to disc 12:15 am
Time 28 min.

So you see my time is long compared to SPP.

My tests were using Sony +RW dvd disc. Been using these for 4 years
use TDK now Maxell -R disc also.

Thanks for the reply. This is certainly more in keeping with my results using SP on the 537. I also contacted Magnavox and asked about the dubbing time. They said 25-30 minutes is about right for 2 hours of SP content on the 537. This is significantly slower than my Toshiba, but it's not a deal breaker as long as nothing is wrong.

one final

Test 3
Length 1:32:27

Start 12:58 am
Writing to disc 1:20
Time 22 min.

Each time the Sony +RW was erased.
After viewing SP looks the same as SPP to me.SPP with 2:30 recording time is good
for editing long movies.

Each test was HDD>DVD in SP.

I have some stuff in HQ I will record later. One is 3 hours long so I will Divide it into 3
and record it on 3 Disc's
