Here's an odd problem. I've just recently set up MythTV for the first time and have been using it for a few days. Yesterday, I noticed a few programmes recorded where commercial flagging had failed with an error, unable to open file.
I went looking in the recordings folder and thought it might be a file permissions problem. mythbackend and mtd are both run at startup as root and mythfrontend is run after logging in as mythtv. Most of the recordings files were owned by root with file permissions 644. I changed the existing files' owner and group to mythtv and set the setuid and setgid bits on the folder with the intention of making all new files owned by mythtv. The result is not quite what I expected. Every file since then has its group as mythtv but its owner is either mythtv or root in a pattern which seems random, and I can no longer watch any recordings. When I select a recording in mythfrontend, it takes no action when asked to play it. I'm assuming this is a problem with what I've done with file and folder permissions, since I can still watch TV and videos (which are in a different folder). The question is, with the backend running as root and the frontend running as mythtv, what should the file owner and permissions be for recordings? And if the file's owner is mythtv, why would either the mythtv user or root have any problem accessing it? -- Best regards, Derek
