It looks like it has some issues when playing back standard DVD's.
The HD-XA2 performed well on my HQV Benchmark test DVD, but not quite as well as I expected. Static detail was excellent, but the player stumbled through the first two deinterlacing tests, leaving jagged edges apparent on the moving bars. On the test's bridge scene, used to evaluate detail preservation and image enhancement, it was a complete mess, with jagged edges present in stairs and significant blurring of detail within the bridge's fine brickwork. Experimenting with the video-processor settings, I found that disabling the block NR feature brought the detail back, but jagged edges along the curved stairs remained. Though the processing prowess of the HD-XA2 surpassed that of the Sharp HDTV, it was not even close to the performance of the (relatively expensive) Realta HQV processor unit I use when evaluating HDTVs.
