Blockbuster has posted lower than expected quarterly revenues and same-store sales, blaming stiff competition for its performance.

The DVD rental chain made a net loss for the second quarter that narrowed to $39.7m (£24.3m) from a net loss of $44.7m (£27.3m). Revenue fell nearly 22% to $1.02bn (£623.9m). Chief executive James Keyes said the retailer plans to increase the number of DVDs available in stores this quarter.

Meanwhile, Blockbuster has been rolling out its own kiosks at grocery stores and other retail locations.
