I stay away from anything that has only s-vidie or composite video imports if you want to use your monitor as a viewing device.
Pay an extra 100 or so and get yourself a Key Digital X-blaster [KD-XB] or its more expensive [but with wider support] the KD-CTCA2. Both: 480p, 520p, 720p, and 1080i with automatic switching, but the KD-XB only guaranties support for the Xbox and GC [PS2 and Progressive Scan DVD players are a crap shot according to their technical support service].
The KD-XB can be had for about 170 new.
The KD-CTCA2 will net you about 250 new.
