That all depends on what connections you have available. Basically, you want to use the best inputs possible to your TV. In terms of signal quality, the connections available, in order, are:
HDMI - best
Component Video
S-Video
Composite Video
RF (coax cable) - worst
You want to connect the device with the best picture quality (DVD) to the TV using the best signal you can, so if both player and TV have HDMI, use that. Otherwise, use Component.
I ran out of inputs on my TV before I ran out of things to connect to it, so what I ended up doing was running the output of my VCR into the input of my DVD recorder, and connecting the DVD recorder to my TV (using COMPONENT VIDEO). This causes some loss in signal quality, but the VHS quality is so crappy compared to the other inputs, I didn't really care.
The video switches you're likely to find for any reasonable price will only switch composite (analog) video signals, and so are not the best for today's high quality video signals.
You can buy a switch box at any electronics store. It'll have aud/vid input for several devices, an output cable (that plugs into the tv), and buttons or somesuch to change which device is active. The input ports are usually found on the back of the TV, though there are often some in front, too.
