Thanks KAD. A couple of questions though...
1. what is stock.osd.bin?
2. Are you saying that I can use the instructions at the start of this thread to change the existing cramfs file to EXT3? - apologies for the 'un-educated' questions but I'm new to all this linux stuff!
3. What is the command 'svn' as I' getting a message saying this doessn't exist?
If I mount psychothc_mod_6_5_3-svn62.osd.bin then copy the files to a new directory on my usb drive connected to the WD and then make the changes to the files in the directory on the USB drive can I then copy all the files to a empty ext3 filesytem that I've previously created and monted? - would that work?
For info - I'm using psychothc_mod_6_5_3-svn62.osd.bin and want to change the colours of the 'Options' bar from red to a different colour. This is a cramfs file as opposed to the standard psychothc_mod_6_5_3.osd.bin - I'm using the 'svn62' version because I want MediaMark to work and it doesn't in the original version.
Is anyone using an EXT3 filesystem version of psychothc_mod_6_5_3-svn62.osd.bin ?
