It's the one on Recovery you want to change not the EFI one, just fsck.hfsplus /dev/sda2


- jelleeelco - 2010-10-24

I tried the following right at the beginning:

sudo fsck.hfsplus /dev/sda2

I got the message that fsck.hfsplus was an unknown command. Should I do it without sudo? I'm running the latest Ubuntu Live CD... can it be that that command is not in there (maybe a very stupid question...) Sad


- jelleeelco - 2010-10-24

Yep,.. just tried what you said and it gives me the following message:

The program 'fsck.hfsplus' is currently not installed. You can install it by typing: apt-get install hsfprogs
you will have to enable the component called 'universe'

Does this mean I will have to install Ubuntu to my main computer, boot in there and get the program?

Will find out on google what the program does. But I guess I am limiting myself by using the Live CD and not having Linux installed on my computer. Is that a fair thing to say? At least I have something to work on...


- Sam.Nazarko - 2010-10-24

Sounds like you don't have basic HFS file support. Install it, and try again


- jelleeelco - 2010-10-24

Sam, I am just running of a cd with ubuntu live. I guess its limited. I am glad that at least now I know what to do!
I'll install linux to my pc and try again (I start to enjoy linux!) Many thanks for your help, I look forward to your new images!


- Sam.Nazarko - 2010-10-24

Just run it in a VM Smile


- jelleeelco - 2010-10-24

Oh man...this is driving me nuts!

I have installed the linux to my pc. Setup the necessary program what you mentioned. Run it and it said that the partition Recovery is fine.

Again, tried to change the boot file but it STILL doesn allow me! What do I have to do? How do I get this read-only to be write-enabled?

Iḿ using VI editor, and saving with :w! but it still comes back with E212: cannot open file for writing....

What am I doing wrong?

--> just had an idea. If I use my "new"Linux pc to create the USB stick, wouldn't that give me automatically all the rights to it? The previous sticks were created with a windows machine (pc from work)...Going to try this, fingers crossed...


- Sam.Nazarko - 2010-10-24

Okay, put the USB in:

First unmount Recovery as it will automount

Code:
sudo umount /dev/sdXn

where X is device letter, n is disk number. Most likely B, 1

Next, fsck.hfsplus the volume:

Code:
fsck.hfsplus /dev/sdXn

Now, force the drive to mount with r/w

Code:
mkdir mnt
mount -t hfsplus -o rw /dev/sdXn mnt

Next edit the com.apple.boot.plist

Code:
cd mnt
sudo nano com.apple.boot.plist

Done - so now you clean up

Code:
cd
sudo umount /dev/sdXn
rm -rf mnt

Problem should be solved. Try not to post in two threads with the same problem next time. Let me know how it goes.

Big Grin Hi Sam

This worked beautifully! Tried it first thing this morning and all is ok now!
Many, many thanks for your (and Scotts) help. I now understand as well what the issue was...(mounting without rights...). I would have never come up with that!

Now running a very silent and very cool ATV from a very fast USB stick Smile

Humble apologies for posting in two threads....Blush

I'm gonna bite the bullet and go this Crystalbuntu install. It sounds like it will reduce the playback stutters I'm getting at the moment.

Just two little questions, both of which have probably been covered, but this thread is over 100 pages now.

First, I assume the minimal install version will have better performance. Is this the case?

Second, are the download links on the top post the latest version, or are there newer ones somewhere further down the thread?

Sorry for probably asking repeat questions.

Cheers

I tried the minimal install from a USB stick. Very impressive, but it forced me to ssh in and reboot after leaving the ATV to rest for a while. This happened enough times that I went to the OSX install with beta2 of Dharma. Since then it's all been fine. My next step is to try the full version and not the minimal one and then the new one that is currently being talked about. The Linux version is zippier, but I prefer being able to drop down to OSX in an easy way ( which is why the beta 2 version of Dharma has been great for me).

Playback issues of MythTV recordings - belmore - 2010-10-26

I've been having problems with stuttery/unsmooth video and slightly out of sync audio when playing back some Myth TV recordings. If I turn off the crystal HD acceleration, the issues go away. However, if the recording is 1080i, it's plagued by interlace artifacts.

I started with the minimal linux install from the first post of this thread and updated to the latest XBMC svn build and the latest Crystal HD driver (R172).

I've included my dmesg output and xbmc.log from a typical example, playing back the first few seconds of a Cougar Town episode.

My dmesg output is here:

And my xbmc.log is here:

http://pastebin.com/WqdNuYEm

Movie rips seem to playback w/o issues. Any suggestions would be greatly appreciated! Thanks!

I'm not having this problem (simply clicking a button on the apple remote brings XBMC back to life), but I updated to the latest svn version of XBMC. And earlier post on this thread covers the steps to upgrade:

Good luck!

[ATV/Crystalbuntu] Perfect playback at 23.97/59.94 Hz - simonp - 2010-10-26

Huge thanks for the ATV/minimal ubuntu image guide. It got me up and running an my internal drive in no time. Long time lurker but just registered for the first time today to post. Now that I'm on linux I've been perusing the linux forum and ran across this thread:

http://forum.xbmc.org/showthread.php?tid=70068&page=5

I'm looking for smooth 23.97 hz playback and I'm wondering if following the guide in the above thread should be my next step. Has anyone tried it? Is it necessary?

Thanks!
