Alright, so after a thorough review I've encountered the following.
In Tomb Raider, the FMVs possess an audio skip (plays fast for a split second, giving a squeaky effect) every 30 seconds or so. The game also tends to hang for 5 seconds when entering the inventory screen. Other than that it was a solid experience.
As for carmageddon, I've been suffering some other issues. I'd imagine this is completely with how DOSBox handles mounting disc drives. When I play the game with the carmav.exe it always asks for the disc even though it is present. Obviously using voodo2c.exe alleviates this problem, but then I don't get to view its FMVs. Since the disc is still not present as far as DOSBox is concerned. Ironically, when I go through the process in DOSBOX (w/o using glidos) the game plays fine w/ FMVs (granted I could only get it to work with hires.bat), any of the other executables encountered a dll problem/error.
None of these are really that big a deal, but at the very least I'd like input in regards to the 5 second hang with TR.
