I recently purchased a Philips 32" HDTV (32PT830H). I do not yet have an HD tuner, so currently the only source I can plug into the HD input (via component video cables) is my JVC Progressive Scan DVD player (XV-S62). During playback of a DVD, the screen size will occasionally zoom in and out rapidly. The amount of zoom is very slight and happens in a split-second. This only seems to happen during the first 30 minutes or so of playback. It does not occur when the disc is paused. If I open an on-screen menu for the TV settings while the glitching occurs, the menu text will zoom in and out along with the DVD picture. Also, this problem does not happen consistently. I am having a hard time determining whether it is something wrong with the HD portion of my TV, or if it is the DVD player putting out a random glitch. I still have 2 months of warranty left on the set, but I will still be a bit paranoid about future failure even if it is fixed. Has anyone had any similiar experiences?
