Lets say I have decided to dedicate a desktop for the sole purpose of a PVR rig, lets also say that the desktop (IBM NetVista Pentium 4 model number: 6790-21U) uses half height (low profile) cards, now lets continue to say the operating system is Win XP Pro SP2. I have realized that I do not want to "tie" my primary rig up with additional components. Also I am thinking of connecting a KVM switch from the PVR rig to my primary rig. I really do not need to watch TV on my primary rig, I just wanna schedule and record shows and be able to send them back to my TV. My questions are the following: 1. Find best possible PVR solution for my PVR rig's "half height" problem. Perhaps a USB TV tuner? 2. Do I really need a "good" graphics card in the PVR rig if I do not plan on watching tv on my desktop? 3. Could I in theory hook up a KVM switch just so I could bounce from primary to PVR rig? (do not need another monitor in the room, to messy as it is). 4. Will I have any issues running Win XP Pro? I hope this makes sense to you? I just want to "tuck" the PVR rig away and access it through my primary rig.
