I used a 2002 Football TDK High Grade tape for this test- recorded at EP mode. You may say well this is not a good speed. You are full of BS. This is exactly what we want. I recorded both burns to a DVD-RW and played them back on the Panny XP-50 which is a Top 7 in Home theatre Secrets----still. The 2005 Panny ES10 burn beat the 2005 Pio 531 for video quality decisively when played back. But do not think the 531 is bad. It records better DIRECTLY from cable or Sat IMHO then the 2005 Pannys.
