其实每次重灌之后都会忘记设定是啥，爬文又都爬不到。
偏偏几篇旧文里面不是没有解答就是推文里面叫人去爬文。
我到MLB.tv的Q&A找了半天有找到教学，可是真的不太好找

里面第六项有教学，他说...
6. What are the optimal configurations for my media player?
For the Windows Media Player Series 9, use the following configurations:
这是是WMP9的设定
a.Pull down the Tools menu of your Windows Media Player Series 9 (or
right-click on the embedded video screen) and select Options.
在WMP9的视窗中拉出工具=>选项，或是直接在画面上按右键，选取选项。
b.In the Player tab, be sure the "Download Codecs Automatically" box is
checked.
(这个部份要在WMP里面选才看的到)，选取播放程式标签，勾选自动下载转码器。
c.Also, be sure the "Connect to the Internet (overrides other commands)" box is
checked.
此外并勾选连线到互联网(覆写其他命令)。
d.In the Performance tab, in the Connection Speed category, select Choose
Connection Speed.
(这边开始都可以在mlb.tv的画面中右键选项里找到)，选择效能标签，
并勾选选择连线速度。
e.In the Connection Speed drop down menu, choose the speed proper to your
Internet service. Note: For MLB.TV, the speed must be higher than 350K. If
you do not know your connection speed, contact your Internet Service
Provider.
下拉选择连线速度的选单，选取适合你的速率。(我是都选T1啦)
f.Select the Network tab.
选择网络标签
g.Uncheck the top two Streaming Protocol circles: Multicast and UDP. Leave TCP
and HTTP checked. (You can also try and uncheck TCP.)
不要选取多点传输以及UDP，只留下HTTP以及TCP。(也可以试着取消TCP)
h.Below in the Streaming Protocols section, click on the HTTP protocol.
在下方的proxy设定中，选取HTTP的proxy设定。
i.Click Configure.
点选设定。
j.Change the Proxy Setting to Do Not Use a Proxy Server.
将proxy设定改为不使用proxy。(但是我发现HINET用了proxy比较顺。)
k.Click OK to the Configure Protocol window.
点OK。
l.Click Apply.
点套用。
m.Click OK to the Options window.
点OK。
就好了。虽然我是用WMP10，不过大致上设定差不几多。
我跟着他这样弄之后，就没在LAG过了，天天快乐的看condensed game。
