S1, Dell's ok
Perhaps the Sony is using a codec that Premiere needs to know about.
The slow playback in WMP is likely due to the h u g e file size of the captured video from the Sony. Maybe try a copy from the DVD of the clip you want to a local hard drive would help WMP.
Not to say that another here in our forum may not have an answer, but adobe has a support forum area at

I have an older vers of Premiere ,and an older vers of computer
, works nicely - so (eventually) yours should too.
