Last year's inaugural series of "Metropolitan Opera — Live in HD" was successful far beyond what most observers had anticipated. So the program has been considerably expanded: there will be eight operas (up from six) included in the 2007-08 series, and they will be seen in roughly three times as many venues in North America as last season. Other countries with participating theaters include Australia, Austria, Belgium, the Czech Republic, Denmark, Germany, Japan, the Netherlands, Norway, Puerto Rico, Sweden and the U.K.

Many of the participating cinemas will offer weeknight encore presentations of the operas in addition to the live transmissions.

Earlier this week the Met revealed that the New York City public school system is participating in this season's simulcasts, most of which will be shown at one designated school in each of the city's five boroughs.

Within 30 days of each live transmission, the video feed of the opera will be available on demand as pay-per-view television via iN DEMAND Networks. As with last season, PBS will televise all eight Met broadcasts subsequent to their theatrical showings, and EMI Classics will release five of this season's simulcasts on DVD.

In the U.S., tickets are $22 for adults, $20 for seniors, and $15 for children. (At many of the venues, tickets sell out ahead of time, so order early.) More information, including theater locations and links for purchasing tickets, is available at www.metopera.org/hdlive.

The schedule for the rest of this season's "Met in HD" presentations includes:
