PS3 Install Problem

[sega4life]

Got Valkyria Chronicles last week, installed it to hard drive and I could not get passed the 3rd scene because it was stuck on the loading screen with music coming in and out, as if it was skipping and couldn't get a chance to fully load..

I uninstalled the Install and the game worked perfect..

Now I just got Gran Turismo 5p, I had to install it and doing the same thing as VC, but only at the opening movie.

it's as if I'm watching a streaming movie on 56k, plays then stops, plays, then stops..

Any suggestions?

I have a Day One 60gig (now120gig) PS3
