Re: [xine-user] final test

[<fal...@on...>]

Siggi,

Thanks for your help; I just written as root:


chmod 666 /dev/hdd

and now the results are the same for root as for any user.

This situation, with the dvd link created but the permissions still not
enabled
for users could be the same for others users. Perhaps should be a good
idea put
the appropiate instructions to enable read/write dvd-permissions for all
users close to the recommendation about how to make the link.

Anyway, thanks so much for your quick answer and congratulations for the
application.

This is actually your problem as normal user.

here, the check fails (Permission denied), and the script gives a
confusing message, as it assumes that DMA is disabled. I'll look into
that...

[as root]
> [ good ] DMA is enabled for your DVD drive

This one is correct.

No, it means that your DVD drive currently has wrong permissions, so it
doesn't allow you to be accessed as normal user. (not at all...)
When you fix this, it will run fine with your account.

It's definitely a bad idea to run xine as root, as it could quite easily
be tricked into doing anything if some malicous person would give you a
specially prepared stream. ie it's a great security risk, and the next
version of xine-check already contains a warning about that...

Cheers,
        Siggi
