[EX Q]: Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...
[EX A]: Negative

[EX Q]: I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.
[EX A]: Negative

[EX Q]: This is not Lighthouse. This is the ST Luke UMC Lighthouse Praise Band. I am returning it to Amazon because it looks like Chrstian filler.
