"More info about codecs at: Using Codecs"
Very interesting and simply explained. Tho not necessarily easy to fix a problem.
"If he can try running CDs and DVDs to see if there is any problems with sound/video there. If not, it's back to email and WMP 11."
Dad does some surfing with his computer, prints cards, checks ebay periodically, some genealogy but email every day. From what I see, he opens/sends limited attachments. I would be surpised if he has a cd, I know he does not have a dvd. All the audio/moving things that I receive from him iare imbedded in the email(what is that called,by the way?), they are not attached. This one particular email that we've been working on(there are others) is an attachment, and is Windows Media Player. He gets no audio, I get no video. This is really not important to me, unless it can be fixed easily. I would rather you help him with his problem. He also says that as he gets limited emails with WMP, if it is too hard to remedy, so be it.
