BasestationKotaku has an overview on watching TV on your PSP using Sony’s LocationFree TV “watch cable TV, DVDs and DVR from your home entertainment center anywhere you can access a broadband connection. The one (major) downside is that you have to fork out about $350 to buy the LocationFree TV base station.” – a commenter on the site also mentions “you can use it to play PSX/PS2 games on the PSP. Granted there is a slight lag, but it does work.” Link.
