the lg optimus black has a ti omap 3630 chipset with IVA2+ hardware accelerator to decode video,unfortunately the iva2+ can decode only avc baseline profile at 720p and main profile at 480p, but the avc high profile is not support by IVA2+
Luckily the ARM CORTEX A8 CPU has a powerful media processing engine called NEON which can decode video using software codecs which can drain the battery quickly in case of decoding hd avc high profile videos
in the change log of gingerbread update for optimus black, they mentioned support of new media formats as avc,mpeg4 and some users reported that the phone can play hd 720p avc high profile videos, other users reported that it can play 720p mp4 avc high profile and 480p mkv avc high profile smoothly and that 720p mkv shutters or lags.
that means lg have added some neon optimized software codecs that use use the cpu to decode avc high profile video, resulting in faster battery drain than hardware codecs and also im not sure if 1 ghz cortex a8 cpu with neon can play smoothly 720p avc high profile videos because when i play a 720p avc high profile video on my laptop, it consumes more than 1 ghz on the cpu which is pentium dual core 2.3 ghz with ssse3 media processing engine which i guess is much more powerful than arm cortex a8 neon
so what do u think guys?
