I am talking about software to be able to play my burned movies on my laptop. I have tried everything: K-lite Mega Codecs, Intervideo, Windows Media player, Super, AC3 Filter, etc. Retail DVD's will play just fine, but not the ones I have burned. However, they play great on my other PC and on our standalone player. Laptop is an older IBM Thinkpad, with a Matushita DVD drive. It just plays CD's and DVD's but has no burner. There has to be some kind of software out there. When checking GSpot, it showed a problem with missing files from Intervideo which I supposedly corrected. Other than that, I am at a loss.
