If I understand your first two lines correctly, you're trying to isolate just the filename, without '.avi'. You can use the /b switch, along with /s, to get a bare listing, and then parse out the filename on the fly.

File::Find would also be an excellent choice, but I'm just commenting on the code you have.

The two patterns are almost identical, so just anchor the second one, use a character class ([xe]), and you should be good.

And lastly, you can put most of that into the for loop, and use the regexes on $_ instead of creating temporary variables. 

for( map{ s/\\*([^\\]+)\.avi\n/$1/; $_ } `cmd /c dir /s /b *.avi` ) {
   $inventory{$1} = $2 if /^(.*?)s\d{1,2}[xe]\d{1,2})/i);
}

# BROKEN OUT -- follow the numbers
for( map{ s/\\*([^\\]+)\.avi\n/$1/; # 2: isolate filename between last
                                    #     backslash (if any) and newli
+ne
          $_ }                      # 3: pass on $_, not result of s//
+/, which is the
                                    #     number of replacements made
     `cmd /c dir /s /b *.avi`       # 1: get avi files, including sub-
+dirs.
                                    #     dir is a shell (cmd) command
+, so
                                    #     you might need to call it th
+is way.
)
{
   $inventory{$1} = $2 if /^(.*?)s\d{1,2}[xe]\d{1,2})/i);
}
