My sound is behind the visual.
Biz...are you saying that the only way a DVD can playback audio is if it is
48 kHz or is this an amount you want for the best audio playback? Said
differently, will lesser kHz work but just not sound as good?
Do different sampling rates affect sync or not...I'm still confused? If
not, then do you have other suggestions on where I might encounter sync
problems?
You mention that some programs don't convert it properly...is this a
condition that can be witnessed or determined by the user or just an
inherent problem known to exist in certain products?
If the program doesn't convert it properly, then does this mean that the
expected results could be considerably less or more than the value desired?
Can the capturing process (VHS to hard drive) have anything to do with my
sync problems or is it more likely the software's ability to convert this
information during the making/burning process?
If it is determined to be the program that is at fault, then do you have
recommendations on other software in the less than $200 price range that
might net me a better finished product?
Thanks
