I am a newbie to this (most) blogs, so pardon my lack of finesse.
First, it appears you don't get thanked. I understand so THANK YOU.
I have a HP ProBook 453-0 running Windows 7 Professional - 64-bit.
When I load videos from my Memory Card, they play video but not sound.
Loaded and installed [ K-Lite Codec Pack 64-bit 9.7 - Mirror ], and did a RESTART. Same problem. Did not try other downloads. Thought I'd ask first.
