ExtremeTech reports Intel product engineer and blogger Aaron Brezenski has written a blog post to explain the G45's video woes. Basically he says bugs in third party software were to blame for the bad performance of the G45 IGP in video tests:
In his blog post, Brezenski said that the low scores -- 30 out of 100 on the HQV test -- were due to third party software.
"While I question the value of some of the HD HQV tests when evaluating Blu-ray (a topic for another time), they are in fact valid tests," Brezenski wrote. "My sources (I do have some-- really!) tell me that Intel's less than stellar scores are due to a player software issue: properly configured advanced de-interlacing will result in scores 20+ points higher. Still not perfect scores, but coming within the realm of workable, and my hope is that subsequent driver tweaks will improve this even further."
Brezenski also noted that both the G965 and G35 suffered from stuttering every 15 seconds or so at a 24-Hz display refresh rate on Blu-ray, before support for that refresh over HDMI was unceremoniously pulled in the 15.8 drivers. "More and more TVs are supporting this refresh rate and even using it as advertising copy in their features list," he wrote."But currently on G45, 24 Hz refresh Blu-ray playback, which is of interest to those who want the best video quality, is still broken."
In addition, sending HDMI signals directly to an HDCP TV works, but repeater mode, which is required for 7.1-channel sound or if users want to play Blu-ray content back through a receiver, is also broken. Brezenski blamed the disconnect on software vendors, which do not support the use of repeaters.
