WDLXTV App pack: core-extras.app.bin-0.2

Here is an essential app.bin pack for use in my WDLXTV custom WDTV firmware. The following pack contains the fsck_hfs for HFS/HFS+ users, modules to support XFS and ReiserFS filesystems, and several other filesystem binaries that didn’t fit in WDLXTV.

Simply download core-extras.app.bin, then place it on a harddrive/flashdisk & boot your WDTV with the device connected.

The only additional functionality this adds really is XFS and ReiserFS partition mounting, with hotplugging. HFS/HFS+ users should download and use this, as it includes a binary relating to the HFS. The other included binaries will help advanced users, with such actions as filesystem formatting and tuning.


  • core-extras.app.bin cannot be on an XFS/ReiserFS drive at boot, this is chicken&egg.

  • The system will become unstable if you remove the device containing the app.bin.

Thanks new firmware update

Hi, I’ve tried your firmware cause I need XFS support but with my great surprise I discovered XFS con’t work. WD don’t detect nothing. I putted core-extras.app.bin on a usb key like your instruction. Could you resolve it…please ! I need for my nas xfs support.
Thanks a lot.

<<< edit: without logs I can’t do anything. Go to wdtvforum for general support. You’ll be able to debug your issues there. –b-rad >>>

after i put the file in a drive , and booted up wdtv with your mod, it did not ask me anything.
Is the app added to the system automatically?

<<< edit: telnet in and try:
cat /tmp/messages.txt | grep 'core-extras'
it will tell you whether its been found or not. –b-rad >>>

When you say: “The system will become unstable if you remove the device containing the app.bin.”

Does that mean I shouldn’t ever remove the device containing the app.bin? I’m new to this, I would like functionality with a HFS+ drive I have, but was wondering what exactly you meant by this.

So even after flashing, the drive that was used for flashing the firmware with the app.bin has to remain attached?

Would appreciate any info you can provide. thanks for you hard work. you guys are friggin genius’!!!

<<< edit: app.bin’s are not flashed, they are loaded like plugins upon boot…if you remove a device containing app.bins that the system believes are loaded stability issues ~may~ arise. If the wdtv is off you can remove whatever you want. –b-rad >>>

relating to my previous comment/question:
is the limitation of the system becoming unstable when removing the device with the app.bin present while the system is still running with other drives connected? will it still be unstable if WDTV is booted with a non-HFS+ drive (so that I have to reboot the system without the HFS+ drive connected in order to avoid instability?)

<<< edit: only removal of devices containing ‘loaded’ app.bins while the wdtv is on ~might~ cause stability issues. –b-rad >>>

I use a HFS+ (non-journaled) on my media HDD. I’ve read somewhere, if you do not eject the drive before disconnecting, it becomes read-only on WDTV device.

Is there a way to overcome this? Doesn’t the fsck_hfs do this after OS recognizes a HFS+ partition?

Almost everyday I have to connect my HFS+ formatted drive to a Mac, to get it working on the WDTV again. Because I need RW access on my WDLXTV (for FTP purposes).

<<< edit: no way currently, I might look into making a bit of automagic happen to fix it sometime but I’m busy…sounds like something a donation could expedite ;-) –b-rad >>>

Sure, why not. I’d be happy to support the WDLXTV project.

But I’m afraid I’ll be able to donate you next month (I’ve been bill-shocked by my mobile service provider – 900EUR :( for data roaming)

Question: How do you mount an XFS share? Do you do this the same way you share a NFS share?

<<< edit: yes, that would work if you added an xmount line for it in net.mounts. –b-rad >>>

hey i was wondering, is there a tutorial on how to change the font of the subititles for wdtv, i want to change the font to teen edited, which looks good


<<< edit: font was encrypted on wdtv 1, probably still is. –b-rad >>>

Is this plugin useful as well for the WDLXTV Live 0221 ?

<<< edit: nope. –b-rad >>>

wdtvlive with latest wdlxtv and core-extras.app.bin-0.2.
Cant see the local drive(WD 1.5tb with HFS) in the osd
did a cat /tmp/messages.txt
looks like my drive is mounted

Jan 1 00:00:28 WDTVLIVE user.notice root: Create “/tmp/media/usb/USB1/disken”

<<< edit: core-extras is only for original WDTV. –b-rad >>>

Was wondering, does this firmware support video shuffling?

<<< edit: no, but it could be possible with a dynamic playlist if you are a programmer ;) –b-rad >>>

Will this enable the WDTV to read ‘exfat’ filesystem?

April 20th, 2010 09:15


I have a problem with installation of this package. In general, in which way should I install those .bin packages?

Thanks, as you can see from my mail I am now one :-)

<<< edit: Ask on the wdlxtv forums. –b-rad >>>

hi, i am using wdtv live.. i want to use the its main firmware so how can i do that…

<<< edit: This is not for wdtv live, all of this functionality is already included in wdlxtv-live. –b-rad >>>

I’ve been unable to successfully export my connected 1TB HFS+ HDD for NFS access. Will this app pack help with the NFS problem? I get “possible unsupported filesystem of fsid= required” or similar.

Will this help me?

Love your work

does it support exFAT too?
