Why can’t I download 4K Youtube videos?

QMy friend recently bought a 4K Ultra HD TV. There aren’t many 4K TV programmes yet but I have used Freemake to download videos from Youtube and turn them into MP4 videos, so I thought I’d try a similar thing with the new collections of test 4K videos from Youtube. However, it failed. I searched Freemake support and it said Youtube has stopped providing links to these videos (see screenshot), so the download feature no longer works. I am puzzled. Surely it’s possible to get a 4K test video? I know you don’t recommend Freemake because of all the extra PUPS but I’m careful and therefore don’t have a problem with it.

There are several Amiga emulators, with the most popular being WINUAE (free from www.winuae.net). However, while it’s easy to emulate Amigaos (the Amiga operating system), reading old disks is a different matter. The Amiga’s 3.5in disks are physically identical to PC ones but data is stored on them in an entirely different way. A PC floppy drive just can’t read Amiga disks.

There are workarounds involving special hardware adapters, but none is particularly easy to configure, and there’s the small matter of cost: the Supercard adapter that enables a salvaged Amiga floppy disk to be

Aattached to a PC costs US$99.95 (around £64) plus US$15.20 (£10) shipping, from www.snipca.com/17074.

If you’re not prepared or able to go to this hassle and expense, some Amiga enthusiasts offer disk-conversion services. For example, Amiga Forever will transfer Amiga Floppy disks to PC ones for €5 (around £3.50) a go – www. snipca.com/17075.

But being able to read the old disks on your Windows PC solves only half your problem. You didn’t tell us which spreadsheet you used on the Amiga, but the chances are slim that any modern PC application would be able to interpret its files. A solution would be to install your Amiga spreadsheet program inside a virtual Amiga inside WINUAE. Next, open your spreadsheets and save them as Lotus 123 files, as this will let you open them in pretty much any PC spreadsheet.
