Can you not have both? I've played on servers that have had both.
STV, otherwise.
I thought i set it up so you could change between them on the run using MacNetron's config writer :/
I agree that STV would be better but if people want Replay it should be there at the touch of a (few) button(s) should it be desired. The Replay wont turn on/STV off until the next map though so you'll have to do it before you load map X.
If i havn't set that up yet i can do that for you guys if you so wish.
Umm i dont really know, in fact i only used Replay on TF2 and its cool, i would need to test SourceTV.
Source TV provides a demo file of an entire match that can be viewed from any perspective (all clients, observer points and free view). Replay is fairly limited in that it's perspectively driven by the client and limited to individual life spans.
Replay is fun and amusing but is not very useful for feedback. Especially for the authors who may want to review a match in its totality; which would include anything a replay might produce and more. A service we had provided up until the replay feature was released several weeks ago.
STV works for all Source mods. CSS, TF2, DoDS.
Replay is basically a user friendly extension of the demo recording feature. Any client can record a demo by typing "record demoname" into the console, which will record the game from the client's first person perspective. STV just records it from the server's perspective.
