There is none afaik. That kind of tool would be a major task to do: interpreting track files, car files, their skins, implementing physics .. .vcr file only contains info like: car and track name, position data (x,y,z), some forces (x,y,z), some other secondary info like lap times, lightnings, chat messages, votes .. so on. No graphics included in .vcrs.
If you want to see live dials, just use Fraps while doing your best (thats not easy, at least I'm camera shy
If you don't need live dials, use Fraps with GTR2 Replay function.
