you will find inconsistencies in many translated manuals , and errors too
but this recorder does not have twin tuners or pause live tv , no matter who tells you what
it has two tuners ( not one as mentioned earlier ) but can only use one at a time , so you cannot view one channel and record another channel or source , you can only see what it is recording or use limited functions to view dvd or previous recordings while it is busy
sony may not know the difference , or care , or the significance may be lost in translation
pause live tv is available on humax pvr,s etc and is where you instruct it to buffer the programmes by continuous recording , so you can rewind and watch something you may have missed. the 870 does not do that , but if you have pressed the rec button , you can rewind from a later point back to when you started the recording , but you cannot change channel once its recording whereas a pvr will let you channel hop and still carry on buffering the recording for you
its a common misconception in this recorder forum that pause live tv is on the sony and the pioneer , when its chase live tv and only if you have started to record , as it cannot rewind back to anything prior to the rec button being pressed
so if you were to watch a footy match , and pressed record at the start of the game , and never stopped it or changed channel , you then have the ability to pause live tv , rewind it , chase tv etc , but its only because you initiated the recording before needing the function , it does not do it for you like a humax can be set to do
