ref: DVSM-PN58U2VB(W) DVD multi drive....external burner...I had a lot of problems with this unit at first with the software I was trying to use with it...including what instructions came with it...I also have win XP....I tried several software programs to try to get it to work...no use...finally, got Corel software, a cheap verson on sale, around 20 bucks...thought would try it as was at wits end...never could get support in person for it...an nothing for support with previous software, nor Buffalo....the Corel worked like a charm..no more problems....now, I find that it runs a little slow for me...because of my computor capacity...memory, etc...so, just have to improve upon that as it is an older model..I have had a problem with burning a recent dvd from wide angle to wide angle for some problem...I just get standard 4.9 instead of 16.9 for some reason...I believe it to be maybe the DL dvds using now to get the total dvd data on one disk...an my computor is so slow...but, just used a standard 2.0 usb port...an, sometimes, get the insert a blank disk reading, I just re insert or wait until the message comes up again....still think it may be the slowness of my computor...in process of upgrading that, will see if that is the real problem....never a problem before until the latest long dvd burn....Corel VideoStudio Express 2010 is what I use....
