Probably trolling, but...
1. You can burn anything to a disc, retard.
2. MKVs can be split. Once you split it, you'll find most groups just stick an AVI in there with soft subs.
3. With a little bit of effort, you can make softsubs hard, re-encode it however you like and play it on your fucking X-Box.
4. Buy a good monitor, or hook your computer up to your TV (HDMI to DVI, S-Video, whatever)
