have a look at a sony hxd890 , and then decide if you can live with playing 6 divx files from one +RW disk at a time
and you can always use a pc to convert divx to disk using programs like convertX2dvd , possibly even mkv files , or use some other tool like VideoRedo or womble or whatever to get the original files into a format you can play on the sony ( which is a rebadged pioneer )
the sony will let you connect the sky plus box using its tv out scart socket to line 1 input on the sony , and set to rgb 16:9
and the sony will let you connect a vcr using 3 phono leads into its front line 2 input and dub in real time from a vcr onto the hdd , edit , then dub to dvdr disks
