Archive? What's the point of that then? It's just telly - seen it once, no*
need to see it again.

Good Lhord. What a barbarian. I watch some movies over and over again.

And there's music of course. Lots of people listen to it over and over again.

Hmm. I'm more amenable to seeing things more than once than my wife, but
I've still never gone for the collection of films-which-you've-seen which
seem to be so popular. There's a sufficient turnover of stuff to watch
compared to the amount I actually do watch that I never run out.

Then again, I watch the films - unlike some (not by implication you) who
treat them as background.

Music is different though.

cheers,

That's not how it works.

The presence of a film on the shelf (and the equipment to play it) means you
never actually have to watch it.

So Rod it would appear that apart from cost technically there is absolutely
no reason why the SD card couldn't be king in the PVR world.

This evening I did a bit of experimentation, I converted an hour long TV
programme from my Humax (.TS files) to MPEG 2 and transferred them to a 2 GB
SD card, the total file size was 1.45 GB, and the results on my my 28" w/s
appeared to be equally as good as when played back from the original HD
(allowing for the fact that my Toshiba player only outputs composite video).

I know very little about MPEG 4 but I'm assuming that it's more efficient
than MPEG 2, so it follows that the file sizes would be smaller, can you
give me a rough idea by how much and would be resultant picture quality be
as good as with MPEG 2?

An awful lot of info on here

http://www.videohelp.com/

if you're *really* interested in the technology. Not for the
fainthearted though.

No practical reason at all as far as I can see. SD cards with capacities of
4GB (and rising) are readily available now, and the more we buy, the cheaper
they will become. The more people use them, the more gadgets and adaptors will
be produced to handle them. It all depends on what people want.

Yes I was thinking that something along the lines of a 4 GB SD card becoming
the equivalent of a much higher quality VHS 4 hour tape, but with some kind
of LP option for maybe 8 hours of standard VHS quality. Are you why are you

It would be a simple matter of an onscreen menu asking if the user would
like to transfer program/s to card.. So all it needs now then is for
Topfield and Humax to get their heads together and incorporate an optional
standardised card slot on their new models, I couldn't see it adding much
more than a tenner in the way of additional hardware.

NE1 any experience of getting a windows PC to boot from a flash card or
flash type memory at all?...

Yes you can do it most easily with a compact flash card or equivalent
plus an adaptor that emulates an IDE interface.

However, this may not be very long lived. The problem is that the
Windows monitor writes temporary and other files all over the place and
generally makes a mess. Flash memory devices often have a limited
number of allowable read/write cycles before going tits up.

The technique is much easier to do with operating systems. For
example, with Linux, one can mount all of the filesystems bar one as
read-only. During boot, a Ramdisk is created and files that need to
be RW or temporary files can be put on that. I have this working in
a little dedicated, embedded machine used as a terminal server. It
even has a watchdog timer to reboot if ever needed, but it hasn't been
so far in two years.

If you want to do an embedded type of application, there are some
products around optimised with what's needed. I've used Advantech
stuff a few times with good results.
