[ltp] DVD not working

[Richard Neill]

Sounds like your DVD drive has never had its region code initialised. 
Under Linux, just run "regionset". Mplayer will usually ignore the value 
of the region code, but it must have been initialised to something.

To test the CD-RW, I suggest you run knoppix with "toram"  (assuming you 
have 2GB of memory),  and then eject the knoppix CD, then try to use k3b 
(or just cdrecord). If you haven't got 2GB of RAM, I think that DSL will 
work in 128MB.

Also, try cleaning the lens - sometimes DVDs and CD-Rs are harder to 
read than normal discs.

HTH,

Richard
