I don't know what other hardware you have, so I can't be specific.

If you really want to save what you have I'd just copy the raw files  
off to someplace, either a USB drive, an NFS-mounted drive, a tape or  
even just burn the raw files to DVD, without trying to create a  
"playable" disk.

You might even think about removing the hard drive(s) the files are  
stored on and putting it (them) in another system.

In other words, save the files any way you can, which will depend on  
what H/W you have hanging around or can borrow. You can always import  
them into a new Myth system if you have to.

Then, with the files as safe as can be, start trying to figure out  
what's going on. Test the backed up files and see if they are intact,  
and start testing your system to see if you have a hardware problem  
there. You might have a failing hard drive, a failing power supply,  
bad RAM - it could really be anything. You just have to start  
eliminating things one by one.

You might want to try booting from one of the bootable CDs that have  
a collection of test routines, like:


It does sound like some sort of hardware problem, but it's hard to  
say for sure.

So: save the files, fix the machine, re-install Myth and import the  
files into the new installation.

That's how I'd go about it anyway.
