Sorry to hear you are having issues.
OK , a few tips for you - please read all ///
1 Have a full set of codecs https://www.codecguide.com/download_k-lite_codec_pack_mega.htm
for all your PC's - the older one probably needs a video card update ck if there is one - but may be
hard for the older PC to keep up with all the newer programs - not knowing it's full make up .
Might need to update some parts if so would be cheaper to get a cheaper newer PC.
2 - ( Short version Looping Videos ) Split the video at about the 1/3 mark and then move to the end
blending it back into the 2nd part for appx. 1 to 3 seconds depending on what the animation is
at that point .( practice different amounts of time ) ... That should make you a pretty good loop
some videos are just harder to loop than others depending on the type of animations.( practice )
A GOOD video editor recommended at this point ( see links below which would be updated to
newer versions since thread was made . )
3 - WMV is not better for dreams AVI is the best format for dreams . WMV uses 2 to 3 times the CPU
usage than AVI.
When making your dream video save in any format then using a converter convert to AVI to
make your .dream file.
