so do you have a big bin?
with own DVDs recorded on a tv recorder -
you can keep adding to the disc untill it's full
.... this is known as an open disc - and it uses non standard files to make it all possible
to make it playable on any player you have to CLOSE (finalise) the disc (this writes the information "normal" players need)
so if you haven't closed the discs (most people don't even know the option exists) - unless you buy an identical recorder - they probably won't play ... I'd be interested to know if (say) all sonys are interchangeable (I'd gess yes ... but I don't know for certain) - people only complain when it doesn't work
dvd 101 ;-0
and if anyone knows of any software that will do the job ...
