I recently upgraded from an PVR-150 to a pcHDTV-5500. But it seems that my video card (Matrox G400) now is having issues with the 1080i channels since it only runs up to 1024x768 on the TV (via a composite connection). I'm looking to buy a new card that would be able to handle my normal NTSC TV and show the 1080i content. Any recommendations? Mike
