Is this what you are wanting to do?

Code:
#! /usr/bin/perl -w

use strict;

my $src_list = 'movie.list';

open SRC, $src_list or die "Couldn't read $src_list: $!\n";
my @movies = sort ;

my $dst_list = 'dvd-list.html';
open(HTML, "> $dst_list") or die "Can't write to $dst_list: $!\n";

print HTML "

my basic html goes here";

# Add variable to display "Current Record Number"
my $movieCount = 1;

for (@movies) {

    # The order here needs to be fixed.
  my ($title, $run_time, $mpaa_rating, $genre, $prod_company) = split ':', $_;
  print HTML "tr";
    # Make sure we get no undef vars.
  print HTML "td $_ /td"
      for map {$_ || ''} $movieCount $title, $run_time, $mpaa_rating, $genre, $prod_company;
  print HTML "/tr\n";
  # Increment $movieCount by one with each display
  $movieCount++;
}

print HTML "/table
/html";

Notice that all I did was add the $movieCount variable declaration above the `for (@movies` line and added a post-fix increment to the $movieCount variable after the `for map` line so that after each loop and display, $movieCount will increment.

If not, please let me know.

     -h       prints usage information and available presets

     -v       sets the console output to verbose

     -q       sets the console output to quiet

     -prog    shows progress during the export (default with -v)

     -p | --preset name
	      converts the source media to an output file using the specified preset. Use --listPresets to get the full list. Common presets are:

	      lists the available tracks in the source media. Must be used with the --source flag

OPTIONS

     -adr number    a limit value for the data rate for the audio track in bits per second

     -af fourCC     sets the format of the audio output using a fourCC eg. aac

     -sr number     configures the sample rate of the output in Hertz. eg. 44100

     -th number     sets the height of the output video in pixels

     -tw number     sets the width of the output video in pixels

     -vc fourCC     sets the format of the video output using a fourCC eg. avc1

     -fr number     sets the frame rate of the output video in frames per second

     -kr number     specifies how often keyframes appear in the output video

     -fr yes | no   sets whether or not to enable frame reordering (b-frames)
