como separar los videos

coloca <br /> entre medio de los códigos.

dame un ejemplo

¿así?

<br />
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/ei6xgMNoz6o&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/ei6xgMNoz6o&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
<br />

<br />
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/Synwfw8szvw&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/Synwfw8szvw&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
<br />

<a href="http://el-ciego-en-la-web.es.tl/" target="_blank"><img src="http://el-ciego-en-la-web.es.tl/sig.png" width="500" height="60" border="0" alt="el-ciego-en-la-web.es.tl"></a>

mmmmm.

así: fijate que ese pequeño código, simula un ENTER.

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/ei6xgMNoz6o&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/ei6xgMNoz6o&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
