I tried getting a 480p image from my JVC I'ART AV-27WF36 television, but when the progressive scan signal was sent, the picture was doubled, split half-way down the screen. I'm using component cables in the component input. I figured this TV supported progressive scan since it has component inputs, but now I'm not entirely sure. Does this TV model actually support 480p?

Classic sign of failed convergence. You can get the JVC AV48WP74 Convergence repair kit from www.tvrepairworld.com which contains the two IC's and associated resistors plus has the CD with detailed repair instructions.
sounds to me like the differnence between watchiing in progressive and interlace. these older tube tv's are not capable of displaying a progressive scanned image. like the first dvd players. check your video out settings on your ipod to make sure its an interlace output.
On a Philips TV the only way I know to switch to any of the inputs is by scanning using channel up or down. This model is capabable of 480P input only at the CVI/Component input. This is not a HD television. It is only a EDTV (enhanced definition) if you try and input anything iver 480P IE: 720p or 1080i, the double image and/or lines is what you will get.
If you are using the component inputs it will select 1080i automatically IF that is what it is being sent. Make sure your device (cable/satellite receiver) is set to 1080i. The TV recognizes 480i, 480p(progressive scan DVD player) and 1080i. It DOES NOT recognize 720p. Since it has no HDMI or DVI input it can't do HD DVD or "upconvert" DVD but it does very nicely with 480p/progressive scan.
