Nope. Thanks for the idea. Permissions were OK. Changed group on /dev/dtv
to video, tried permissions at 777, still no joy.

Didn't make any special settings for this.

Yes and Yes. I do on both.

Maybe at your house. Not at mine so far.

I've been having an exceedingly difficult time prying the lid off this
particular box.

I saw something on a post about v. 0.17 and the HD3000 that says this
message might mean that your kernel is compiled with a slightly different
DVB API. Does this make any sense? Do I have to try to recompile the
kernel? (Installed it as "linux-image").

Any other ideas on this?
