$mostview on channel_detail.tpl

I would like each channel's most viewed section to have 25-30 videos listed instead of 5. I've tried searching the forum, but couldn't locate an answer. Does anyone know how to properly alter the $mostview section of the channel_detail.tpl file? Here is the snippet:

Code:

---

<TR>

{section name=k loop=$mostview}
<TD style="WIDTH: 20%; TEXT-ALIGN: center" vAlign=top>
<A href="{$baseurl}/view/{$mostview[k].VID}/{$mostview[k].title|lower|regex_replace:"/[^a-z0-9]+/":"-"}/">
[img]{$tmburl}/1_{$mostview[k].VID}.jpg[/img]</A>
<DIV class=moduleEntrySpecifics style="FONT-WEIGHT: bold; PADDING-TOP: 5px">
{$mostview[k].title}</DIV>
<DIV class=moduleEntrySpecifics>By:
{insert name=id_to_name assign=uname un=$mostview[k].UID}
{$uname}</DIV>
<DIV class=moduleEntrySpecifics>Runtime: {$mostview[k].duration|string_format:"%.2f"}</DIV>
<DIV class=moduleEntrySpecifics>Views: {$mostview[k].viewnumber}</DIV>
<DIV class=moduleEntrySpecifics>
        {insert name=comment_count assign=commentcount vid=$recadd[j].VID}
Comments: {$commentcount}
</DIV>


<SPAN class=rating>
{if $mostview[k].ratedby gt "0"}
{insert name=show_rate assign=rate rte=$mostview[k].rate}
{$rate}

(rated by {$mostview[k].ratedby})
{/if}
</SPAN>

</TD>
{/section}

</TR>
