Dvd compatible mode on Toshiba Rdxs32?

What exactly is the dvd compatible recording mode on my toshiba rdxs32. I have had it turned it off yet have still successfully recorded from the tv and burned to dvd-r with no problems. Bit confused now.

Also, what region are dvd-rs burned by the machine? No region?

Thanks.

DVD compatible mode - my specialist subject... :)

There are 2 aspects to DVD compatible mode on the XS32. One relates to something obscure with Nicam (analog) audio, how to handle it if one language is on one channel and a second one on the other. The "Mode 1" and "Mode 2" has to do with which language you get... I'm 99.9% sure this never happens on our broadcasts, so how you set it doesn't matter. Most people set it to Mode 1 "just in case".

The other aspect has to do with the resolution used when the bit rate is between 3.0 and 3.8 inclusive. In this range, if DVD compatible is set to off, it will use a non-standard resolution, which is valid for -VR but not valid for DVD-Video (on DVD-R or -RW).

So basically, unless you somehow find one of these funny Nicam broadcasts, OR you use a rate between 3.0 and 3.8, it doesn't matter how you have it set. But if you record a programme with a rate between 3.0 and 3.8 with "compatible mode" off, you won't be able to do a high speed dub to DVD-R.

I keep mine set to "On, Mode I". That way I know the recordings will always be compatible. The only reason you would want it off is if you were recording to RAM with a rate between 3.0 and 3.8, in this case you'd get a better picture with the mode OFF. This is why there is a note in the manual saying that picture quality may suffer if DVD compatible mode is on with rates of 3.0 to 3.8.

As with all DVD recorders, your recordings will be region free.

I found this out, much to my dismay, just the other day. I already knew that the file wouldnt burn to a DVD-R on the XS32, but i had no idea that it used a non-standard rez, too. That would explain why TMPGEnc kept moaning at me when i tried to transfer it to PC.
Live and learn - that's all the fun of the XS32 :)

Yes - and the only way to create a DVD-R (using the XS32 alone) if you've recorded with compatible=off and rate of 3.0 to 3.8 is to do a rate conversion dub. Here you get a "double whammy" in quality. Firstly, the resolution will be dropped to half resolution (lower than the non-standard one used on the original recording). Secondly, you are re-encoding something which reduces quality, and even more so as the original rate was fairly low. (I assume on the PC you'd have to do the same - re-encode it).

There have been others on other threads who hit this: i.e. they recorded a bunch of stuff at 3 hour mode (rate of 3.0) and it looked fine on the HDD. But when they tried to make a DVD-R they got the "double whammy"....

The moral of then story is to read the manual, especially the bit which say to use dvd compatability mode if you plan to burn a dvd.
Admitedly the manual isn't very readable.
I have mine to use dvd comatabiility mode by default, If I know I'm definitly not going to keep something I ocasionally switch it off..

Most Video-Dvd players also have an Rf modulator so will work okay into a Tv without a scart socket.

Thanks for the tips. I have originally left DVD Compatibility "off" and then had to Rate convert to enable recording to DVD-R. However all chapters were lost - is that right or have I boobed somewhere?
I seem to struggle getting chapters in place and then recording to DVD-R - any tips?
I now have Compatability on Mode 1 - will I be able to add chapter markers and record to DVD - R? Can I use high speed dub to do so?

Cheers

Yes chapters are lost on a rate convesion dub, but kept on a high speed dub.

Yup.. another reason to avoid a rate conversion dub. If you've recorded with compatible on yes you can set your chapter points and high speed dub to DVD-R, and get the chapters.

Another thing I would like to know is what dvds can you upload to the hardrive? I have tried two but neither have had the option to upload onto the hdd.

Thanks.

You should be able to copy any DVD-R, DVD-RW, or RAM disc, providing it isn't copy protected (i.e. not a commercial disc).

Am I correct in thinking that you put the recorder onto the Line U channel and then start recording then play the disk?

THanks for info, the instructions are a bit confusing.
