So there are two different kinds of video on the web - streaming and
progressive download. Streaming means the data generating the AV on your
machine is coming down in real-time from the web, is decoded,
display/played and then goes poof for every second. Some commercial
stuff likes this because nothing is downloaded to your hard drive making
it harder to copy. Progressive download is more common. This is where
you play the video as it downloads but it's also being stored on your
hard drive for future playback as well. Sometimes this happens secretly
like youtube in a web browser. The browser caches the video so that if
you play it again or rewind it doesn't have to download again. When the
cache gets full the browser just deletes the oldest stuff out of there.
So progressive videos will store stuff on your hard drive and if it's a
browser cache it could slow things down momentarily if the video cache
triggers a garbage collection cycle. For podcasts and stuff there should
be no impact on performance unless you start pushing your drive to be
95% full or something like that. All bets are off when your drive gets
full and a lot of people like to keep about 10% empty as a good
performance protection.

Hi Ricardo, I was just concerned about taking up too much space when it comes
to playing youtube videos online. I have had in the past a Windows XP computer
that I stored a lot of music files on the hard drive I should point out that
they were WMA or some kid of windows media format anyway this was before I knew
about MP3 files. To cut a long story short, XP computer was crawling along and
when it came to playing youtube videos they kept playing a bit then stopped and
started again. I was just concerned about video files slowing down a computer
that's all.
If there are anyone on the list who listen to apple keynotes by iTunes podcasts
have you ever experienced your mac slowing down on you.
Thanks

Hi,
why do you think downloading a few podcasts would make your computer any
slower? I mean, thats what hard drives are designed to do. Store and delete
information. Maybe over many years, especially if using a SSD but, these are
things rated in multiple years of use before meaningful degradation. Someone
more knowledgeable about such things can chime in if I'm mistaken but, I don't
think this is anything to worry about as long as you have the storage space on
your drive to accommodate. This will not make your computer any slower.

Of course, but if I keep getting apple's keynotes downloaded to my computer and
even if I delete them, would my computer still get slower.
To give an example, lets say I downloaded 10 videos a bit crazy I know but
continuing on form there, lets say I have listened to them all and my Mac has
gotten a bitl slower. Next though lets say I have deleted them would my
computer be as fast again before I even downloaded them?
Thanks

You can always delete the podcast episode when you finish viewing it.

Hi Recardo and Teresa, first of all thank you for the podcast feed I downloaded
an apple keynote presentation and it worked with no issues at all but I only
see one problem with it. That is to do with memory I checked the video file and
it was well over 1. something GB which is a lot. I've got no problem with this
but if I keep doing this for apple's keynotes I am worried that my mac book pro
will become slower over time. However would it get faster again if I did a
re-install. I noticed as well it said play preview of the keynote that you want
to listen to in iTunes. Rather than having it downloaded. Would this play the
whole video? If so I could listen to it without having to download it. Never
the less I am grateful for the feed.
Now for your question Recardo.
My Mac is connected to wi-fi as for my computer I'm sorry to say that I don't know the
technical term for how this is connected. I have broadband a Hub if that helps other than
that I know nothing. Its no good asking my mum because she knows nothing about what the
computer uses for connectivity for the internet. However I do know that having wires is
technically more reliable than Wi-FI. I also have a laptop running windows Vista. After
you asked the question I went to the apple site but I think they have removed the
"new iPad" keynote because I was gong to try it on y laptop to see if it was a
WI-FI fault. Unfortunatly I can't use my PC is out of action for the moment due to a
software update being corrupted which basically just keeps on logging on and re-starting
at the log on screen which is pretty annoying because it requires someone sighted to fix
it for me. I basically can get this done but I can't comment on when I am going to get
the sighted person to do it for me at college. With all this though, When the apple
keynote comes out I can try it on the windows PC I have college cos that's connected over
WI-FI so I can see if that is the problem. I've got the feeling it was my Mac though. We
will se if it happens again in the up coming keynote though! Smiles.
Sorry for the long post!

Hi all, as I'm sure many of you are aware that Apple's WWDC will be happening soon which
discusses all new and up coming things in the world of apple. After the live
presentation, it is available to listen to on their website however, I have incounted a
problem with it. For example when listening to the "new iPad" presentation,
that happened around in March, I kept getting freezes when the video was playing. In this
case though I would miss a few words and then it will pick up audio again. If any has
youtube and have played a video where it keeps freezing and you have to pause it so it
can buffer it more quickly then this is basically the same thing but with the addition of
losing what Tim Cook has said. I find this strange behaviour because I have a fairly new
Mac Book Pro 13 inch late 2011 and it has 4GB of Ram so I can't see why it would be doing
this. I have come to the conclusion that at the time it could of been that everyone was
listening to the video after it was posted therefore that is my theory on why it was
doing the above behaviour. It was so annoying and I'm sorry to mention this but I ended
up playing it on my windows PC and the odd thing here is that it just played without any
issues at all. This was with Safari on the Mac that I was having issues with.
So to get to the point, when I next come to listen to WWDC next month on my
Mac, if anyone has experienced the problem that I have, I would be grateful if
you could offer tips or any theories on why my mac acts the way it did. Just to
say one more thing when I play youtube videos I have no problems its just with
listening to the apple's keynotes.
I look forward to hearing your thought and suggestions.
Thanks
Daniel
