Q: Video recording to PVR

I have just bought my first ever Iphone, the Iphone 6+ the video recording... it seems great, the device, it has no expandable memory as known, no removable memory as known, I have 64gb... plenty to my needs if I was doing what I used to do.

We can take brilliant quality videos and photos on these devices, yet it seems to me that it's extremely hard to transfer them to DVD to keep them forever? Of course if we're taking top quality photos we will never want to delete them, and should not have to keep them on a computer. My old way of doing things was incredibly easy, I plugged a video cable into the speaker port and it mirrored exactly what was on the phone! This enabled me to very easily transfer phone videos to my PVR with built in hard drive, to the hard drive and then edit from there, cutting out what was not needed.

The Iphone it seems very hard to take videos of the phone to keep? the devices are memory limited and of course data will need to come off them at some point, why record things though if they cannot be kept?

I cannot record to PVR anymore it seems? there is no support for the yellow video cable? I plugged my red/white/yellow cable in from my old phone and I can here the audio playing through the recorder but no video showing. I cannot do this via HD as the PVR does not pick up via HD it has to be via scart.

It seems my only option would be to get the videos off the phone, then convert them into a DVD format? then transfer them onto DVD, a lot more messing around for something that really should be made simple, there should be no issue with copying videos to my PVR from my personal collection, I own that copyright but it seems a signal maybe picked up on either way even if I could play via HD which would stop the recording going ahead.

To transfer to DVD from computer, I have never really done that, it would be hard to figure out as well, and I would either need to record the full DVD space everytime on each video or waste space by having to finalize the DVD?

My first Iphone, very impressed with the video quality which is like it was seen through my actual eyes all over again, but as for transferring the videos of the phone to keep on DVD, surely it must be able to be done, and easier than the only current ways I can think of doing it, I mean come on it's rather clear people will want to permanently keep their videos, or why go to the effort of recording them in the first place?

Thank you
