[mythtv-users] Troubleshooting: Storage Groups, SMB Mounts and VIDEO_TS Folders

Fri Jul 22 08:56:05 UTC 2011

OK, I've got something of an odd problem that's cropped up this afternoon,
under very specific circumstances.

I've moved two folders that used to reside on a hard drive in the backend to
my NAS, so those folders which used to be:

/media/mythtv-b/Video/Music
/media/mythtv-b/Video/TV

are now mounted via CIFS to

/media/NAS/Videos/Music
/media/NAS/Videos/TV

and obviously I've updated my Video storage group to include
/media/NAS/Videos

The troubles come when I start testing on either of my remote frontends. If
I playback some content in the TV folder, everything is sweet - doesn't
matter what, H264 encodes, VIDEO_TS folders, they all work perfectly.

In the Music folder, single files are fine (typically MPEG2 or H264
encapsulated in MKV's) but VIDEO_TS folders cause it to do something like
the following - to the user, it looks like a very long pause, followed by it
working perfectly fine.
