I forgot all about those. I didn't even use them in my last run.
Edit: I hope this answers the movie question. Instead of trusting my eyes to gauge resolution, let file sizes do the talking.
Edit2: Confirming sound as well. Larger file sizes and just to double check I downloaded the HD music patch. Same file sizes as Steam download.
Edit3: First attempt at running Steam KOTOR 2 with TSLRCM not very optimistic. My computer shut down reporting a serious error on recovery. Second attempt much more succesful. Game launched without problem. Anyone care to tell me the first thing I should notice to confirm TSLRCM is working?
