Shares of Hauppauge Digital ( HAUP) were among technology's winners Monday, surging 48% after the company released software that enables consumers to record television shows for playback on portable video players.

Hauppauge's PC-based "Wing" software can be used with players such as Apple's ( AAPL) video iPod and Sony's ( SNE) PlayStation Portable. Wing can also be used to convert existing TV recordings to the PSP and iPod format. Besides the video players, recorded TV shows also can be played on a PC or TV set.

Pegasus Solutions ( PEGS), which sells information technology to hotels and travel agents, agreed to be taken private by a group led by Prides Capital Partners for about $275 million.

The price represents a 15% premium to Friday's close of $8.26 a share, but is almost $2 below Pegasus' share price when the company announced it was studying strategic alternatives in April. The stock surged 96 cents, or 11.6%, to $9.22 in recent trading.
