Does anyone know the main differences between the Toshiba HD-A1 and HD-XA1? What features does the HD-XA1 that the HD-A1 does not? How much better is the performance of the HD-XA1 over the HD-A1? Am looking to get a Toshiba HD-DVD player soon and am trying to figure out if the extra $300 is worth investing? I will still be buying a Blu-ray player at the end of the year when the Sony or Pioneer is available.
