With the Humax DTR-T1000 I was able to copy from the HDD to DVD Recorder. Does the HDR-2000T allow this?

Copy to DVD?

Yes, but you can also copy SD files directly to usb, these are suitable for creating DVD's without the multiple conversions a DVD recorder has to make.

What's the procedure for doing that?
I'm a little confused because wouldn't I need to first record the pogramme to the HDD, then copy it to USB, then copy from the USB to DVD? Or is one of these steps unnecessary?

DVD uses mpeg2 compression (max 720 x 576 pixels). SD TV digital TV uses the identical compression format. When you record digital TV using a PVR the mpeg2 compressed data stream is copied directly to the pvr hard disk. The copy is identical to the original broadcast. When you play back the recording the data is processed by the boxes built in mpeg2 decoder. This creates the original 720 x 576 25fps broadcast as near as possible to what it was before it was compressed for transmission and outputs it to your TV either by a digital connection (HDMI) or an an analogue one (eg scart). Your DVD recorder does not have the capability to record the original digital data directly.
When you record from a pvr using an an analogue output (best quality is RGB scart), this is what happens.
Your PVR's mpeg decoder decompresses the digital video and audio data which it outputs from say the scart socket.
Your DVDR then takes this analogue data and converts it back to digital (Using a DAC - Digital Analogue Convertor).
The resulting digital data is recompressed to mpeg2 (real time mpeg2 compressor) and stored in a format that can be authored to DVD.
The above process is not lossless, so some quality loss is inevitable and of course can only take place in real time.
If you copy the original mpeg2 files (transport stream container) to a PC via USB, the video/audio data is already suitable for directly and losslessly being used on a DVD. All that is needed is the data be contained in a DVD-VIDEO format.
You can do this using free software, however the best but not free software to do this (and edit out commercial breaks) is VideoRedo TV suite. You can easily add multiple titles with a front end menu to utilise the space you have on a DVD blank.

Thanks very much for the explanation. I'm afraid I'm going to take the path of least resistance and just use the Scart. (slinks away shamefaced)

(slinks away shamefaced)You ought to at least try the free trial of VideoRedo, it's amazingly fast and very simple to use. It can also edit HD H264/AVC content which you can also copy to DVD blanks (in full HD) provided you have a Blu-ray player.

...provided you have a Blu-ray player.
'Fraid not.
I appreciate that your method would give better results, but the Scart output will do for me. I've done it before with the YouView box, so I know what to expect although I hadn't understood about the multiple conversions. Interesting.
So when the DVD recorder is recording from its own tuner, it doesn't need to jump through those hoops, correct?

So when the DVD recorder is recording from its own tuner, it doesn't need to jump through those hoops, correct?It depends on the recording settings. A DVDR with a true pvr capability (requires a hard disc) can record the data stream as is.
If you have different recording qualities HD/SQ etc then this implicitly means the original data stream has to be re-encoded.
The file size you get is directly related to the bit rate. If you make the file size smaller than that recorded by a true pvr then the transmission has to be decoded and recoded with a lower bitrate (which reduces the quality as it discards more of the video data).
The reason you cannot record a external video source with a true pvr is simply because it lacks a DAC and a mpeg encoder (it doesn't need either because the data it copies to a hard disk is already encoded).
Not sure why you want to copy content to DVD at all. These days you can play back recorded content directly copied to a usb mass storage device on pretty well anything. If your TV doesn't support USB playback then very cheap usb capable media players (from about £20.00) can be connected to most any TV.
You can copy hundreds of programmes to a usb hard disk, and play it back almost anywhere.
I can for instance watch content copied to a cheap hard disk using my tablet PC at 30,0000ft in full HD and you could watch the same recordings on the hdr 2000T on your big screen TV by simply plugging the same drive into your Humax box.
For example a cheap 500GB usb powered hard disk can fit in your pocket.
It can hold more content than a 100 DVD disks and can be used almost anywhere.

That sounds like mine - a Sony with HDD.
As for why I want to record to DVD, well, it serves my purpose, I only need it occasionally, I don't have a need to watch it at 30,000 feet, and I absolutely totally don't want 500GB in my pocket. Horses for courses.
I do find the explanation interesting though. Much appreciated.
