I didn't see if you said, but are you wanting the "HD" versions? I know there what's most likely to be hosted on most streaming sites and if that's the case, I urge you to try and track down the original cuts.
The HD versions are notoriously bad. In fact, much of the cinephile parts of the interwebz hail them as the worst remasters ever done. For the most part, they're watchable, but the reason why I ask now is because season 2 is the most affected by their badness. After season 5, season 2 is the most contextually and thematically complex. Throughout the entire season, there are certain frames that are very deliberately staged and lit in a way specific to the theme. And many of those shots are recreated later in the season to form a thematic continuity. Except that, since the way the HD versions were cropped and recolored was completely arbitrary and seemingly random, that continuity is lost. Plus, like season 1, the first half of season 2 was shot on 16mm, which only exacerbates the problems even more.
Also, the sunrises are all the wrong color. And 'sunrises' are really important in Buffy from season 2 on - beyond the obvious of them signaling the end of the vamps' daily jaunt.
Oh and then there's the part where, in one of the most skin-crawly scenes of the season, you can see the boom mic guy hanging out in Willow's bedroom.
