I've linked to youtube before on eBay & never had a problem...
Have TONS of eBaying experience too so PM me if you need any tricks / tips etc.
Trust me there is a BIG difference between a standard eBay listing & a GOOD eBay listing...
(I have sold CDs on eBay auction that ended at AU$280 & someone else listed the same thing no more than a month later & it sold for all of about AU$10).
Could be the difference between a leaky caravan & a solid one!
