Starting to wonder whether XBMC is as good as i thought. Watching TV on another input via the Virgin box has higher definition than anything i'm playing from libraries though XBMC, even bluray ISO files.
I'm not seeing the crispness i do from just watching TV.
You're settings aren't right. Virgin HD will be 1080i at best with a much lower bitrate and MPEG2 encoded so vastly inferior to a Blu-Ray rip.
