Colons in folder names can cause confusion

In the Movie Player, if a folder has a name containing a colon, its contents aren't displayed.

This is caused by the fact that the string format of a serviceref is:

REFTYPE:FLAGS:STYPE:SID:TSID:ONID:NS:PARENT_SID:PARENT_TSID:UNUSED:PATH:NAME

and servicerefs for folders are constructed in Screens.MovieSelection and Components.MovieList using code like:

eServiceReference("2:0:1:0:0:0:0:0:0:0:" + currentDir)

If currentDir is something like "/a/b/c:d", then the string is parsed as having PATH="/a/b/c" and NAME="d", so the path component of the serviceref will be incorrect.

Similar issues may occur if there is a "%" in the path.

There are similar problems in the FileCommander plugin, Components.FileList and in the ShoutCast plugin.

The fix is to change the code to:

import urllib
...
eServiceReference("2:0:1:0:0:0:0:0:0:0:" + urllib.encode(currentDir))

or better,

eServiceReference(eServiceReference.idFile, eServiceReference.isDirectory, currentDir)

Replication steps

In the Movie Player (MEDIA from live TV), create a directory with a name with a colon in it (like "a:a"). Use GREEN Move to move a recording into the directory, and then navigate into the directory. The directory will appear empty.

Return to the previous directory and rename the directory to remove the colon. Navigate back into the renamed directory and the contents will be visible.

Similar problem in FileCommander:

In the Movie Player (MEDIA from live TV), create a directory with a name with a colon in it (like "a:a"). Use GREEN Move to move a recording into the directory,

Exit the Movie Player to live TV, then enter the FileCommander with MENU>Sources>T4, and navigate into the folder created above. Scroll down to the recording's .ts file, and press OK. The recording will not play.

Exit the FileCommander, rename the folder to remove the colon, re-enter the FileCommander, navigate back to the renamed folder, Scroll down to the recording's .ts file, and press OK. The recording now plays normally.

Similar problem in Components.FileList.MultiFileSelectList

This problem only appears in instances of MultiFileSelectList that have useServiceRef=True.

There don't appear to be any such uses in the easy-ui-4 code, so this part of the problem can't be demonstrated.
