Failure to laod programme

Clearly the dvd unit is reading the discs and processing the data ok for it to record on the tape without problem, therefore the problem is either the interface between the tv and the player or a mismatch of signal or signal type between the tv and player.

I am wondering if you have tried a different tv, in particular one of a similar vintage to the player?
How are you connecting the unit and the tv? The usual way and the best way is using a scart lead but the scart system that takes a good analogue signal straight into the sound and video sections of the tv has been going out of fashion for a couple of decades and modern tv sets are accepting only digital inputs, rendering a great deal of useful older equipment useless.

Digital to analogue and analogue to digital converters are available at many prices but I don't know how successful they are.

How old is Toshiba DVR620KU recorder and how long it started this problem?
Does it playback previously recorded discs correctly?
Did you tried lens cleaning disc in recorder to clean optical lens?
These info will help me to suggest a solution.
Thanks.

You will need an analogue to digital converter box. You connect the camera to the converter box with analogue cables and connect the A/D box to the PC with a firewire cable.
Note: Many mini DV cameras with analogue inputs can act as an A/D Converter box.

If the disc playes back then the problem is not with the DVD unit. In order to record white noise, the channel selected for record is probably not tuned in. Try recording the same channel on to video tape and see what results you get.

The analogue video format can be converted only with a conversion software/ harware installed into your PC. This might be expensive and is used by studios for conversion. The analogue video is processed and compressed before it is converted and written to a disc. On the other hand you can use the new camcorders to input the analogue to be written into the drive/hard disc/ which can be transferred to a PC in digital format. Hope you try this out. Good day

Try Finalizing the DVD disc on the Camcorder or the DVD Recorder before trying to copy the DVD on the Computer.

I called the manufacturer and realized I was using the wrong type of recordable DVD disc to dub to. Non copy protected VHS tapes dub just fine as long as I'm using the proper disc.

try alternative software like beyond tv or sage tv.im using beyond tv on mine but i think sage tv works to capture from connections like vcr

Hi 8 tapes are analogue and need to be converted to digital before a DVD can be made of them. You can pass the signal through a digital video camera to the computer to convert them. Only very short videos could be copied onto a CD as most video files are much larger than a CD's capacity.
I'm not sure about digital 8 but maybe the camera only has an analogue output? If the lead goes to RCA plugs - that is analogue. A firewire socket means a digital output.

Try using DVD/RW disks with pausing the recording when you change VHS tapes.
