Hi there,
I used to rip and encode music cd's with grip and oggenc, which works pretty
fine. However, I cannot import the freshly encoded files in
rhythmbox, which pretty much sucks. After indicating the
folder to import, an error messages tells me,
"The file is not an audio stream, file:///path_to_file/file.ogg"
for every single file in that folder.
The files are all given filenames with no spaces, only lower case,
id3, id3v2 and ogg-tags are present, is this an issue?

If I encode by using oggenc via command line, no problem with rhythmbox.

Thanx for any suggestion.

what distro are you using? Have you got the proper codecs and all setup? Have you tried playing in other players like amarok,xmms,banshee etc??

i can play all files e.g. using xmms and ogg123.
my distro is ubuntu breezy on amd64 opteron ws.
codecs are installed.
