This is a question for folks who are well familiar with the options we have available.
To avoid problems for prospective viewers of material .... I often wonder what might be regarded as the safest codec choices when DVD ripping and converting. I find it hard to remember all option details and don't want people to have to scramble to find a suitable codec when playing a file.
Main concerns are choices with .WMV, .MPEG, and MP4 - to achieve pretty much cross-platform reliable compatibility. Sometimes an editing prog employs a default but others give many choices.
So - what are safest choices in other's opinions?
