Video Playback / Recording Devices

Hi. Can somebody tell me the correct way of connecting the following units using the scart leads and sockets . tv, digi box, dvd player and vcr. Thanks.

I currently have a Toshiba RD-85DTSB HDD/DVD Recorder.

I've been trying to create a DVD-video by transferring material recorded on  the hard drive.(Stuff for study)

I bought the DVD/RW discs as recommended but when I load a disc to dub to and then select the 'Dubbing HDD-DVD' option, it says either that

a) there isn't a disc in

 or after five mins loading it says  b) the disc is empty. 

Hello,

 I am looking for some assistance/advice.  I have owned a LG LRY-517 DVD-VCR recorder for about 2 years.  Recently, the machine started to take longer and longer to read DVDs and now will not read any DVDs except ones that are store bought or rented.  I have recorded a lot of programs on DVD using DVR +R and DVD+RW and they have always worked fine.  Now, the machine will not read any of the homemade DVDs made on this machine or others.  I have an older DVD player in the house that reads the same discs fine.
