Ubuntu - What if my DVD playback is jumpy or jittery?

This is exactly why NOBODY wants to use that piece of Crap Ubuntu. Who in
their right minds wants to run cryptic commands?



DVD Playback Is Jittery and Jumpy
When you watch DVD movies on your computer, you may find that they are
jittery and unstable. In most cases the problem is that direct memory access
(DMA) mode in your DVD drive is not enabled. By enabling this mode, your
problems should disappear.

Check if DMA mode is enabled by running this command:

foo@bar:~$ sudo /sbin/hdparm /dev/hdc | grep dma
Most DVD drives are /dev/hdc, but change the letter if yours is different.
If DMA mode is not enabled, you will see this:

using_dma = 1 (on)
To turn on DMA mode, run this command:

foo@bar:~$ sudo /sbin/hdparm -d1 /dev/hdc
Now try to play your DVD.

If this solves your problems, you should edit /etc/hdparm.conf and add the
following block:

/dev/hdc {
dma = on

Quoting advice from when, 2003? I have *never* had a problem with DVD
optical drives, be it for viewing a DVD or for burning. You really are
desperate. The question is why.

I have thousands of MP3s and they played out of the box as do DVDs.
Maybe if you actually install Ubuntu, you can have something intelligent
to say about it.

Bill:

We realize that anything past "point and click through a wizard" is
beyond your simple computer abilities. However, there are quite a few
people using computers who possess actual computer skills and can
easily handle such matters.

We do advise that a simpleton like you should definitely stay with the
point and click, guided, wizard oriented portions of Windows.

BTW - you might want to note that hacking the Windows registry and
inputting hex values is the cure for many Windows issues - that's much
less friendly than the command line that intimidates you so much.

Who is this "WE" you putz? So you say you are looking for people who have
computer skills? Well, +BOB+ you came to the right place. I suggest
getting a book, "Vista for Retards" and maybe after 5 weeks of intense
reading, you just might learn something.

You have it all wrong. You are the simpleton who can't figure out Vista. I
am sure that frustrates the hell out of you. Better seek help.

So you have been hacking the registry trying to get your Vista working? HA -
Better wipe your machine clean and install Ubuntu. That is right up your
alley, douche bag.

"We" is pretty much everyone in the newsgroup except for you. They all
realize that your computer skills end at playing solitaire.

Oh, FYI- it was one of your other sockpuppets who got upset about the
phrase "we" last time. You might want to keep better track of the
various personalities if you're going to play the game. Of course,
since you're not even smart enough to use different newsreaders and
different servers for your various personalities, it's not surprising.
You're about the lamest sockpuppeteer ever.

Where did I say that? I pointed out that you think right clicking the
mouse is a tough day writing OS code, but I didn't ask for help.

You're the one loving the dumbed down interface and railing against a
simple configuration file tweak. So who's the simpleton?

Don't know very much about MS Windows or Vista, do you Bill? Not
familiar with "DHCP Broadcast" fix, the "remember folder settings"
fix, the "can't view PPT files in Windows Mail attachments" fix, or
about 1000 other Vista fixes that require registry editing, eh?

You might want to learn a little about Vista before considering
yourself an expert since your abilities seem to be limited to logging
in and using notepad.

I don't have a need to run Ubuntu on my desktop. That still doesn't
mean I need to denigrate people who do with childish insults.
