Re: Do I need a Codec Pack ?
There should not be any problem with installing a codec pack. Usually you just a need to install a couple of codecs to view your downloaded movies.
It just depends on your needs. If you download xvids only, is one thing. If you're also into all the HD stuff, then you require something more. There's a few packs that arent that good and cause conflict.
I use k-lite codec pack an never had any problem but there's a few people that have reported some problems. But you shouldnt have any conflicts between standard codecs that come with xp and a codec pack. Just never have more than a pack installed at the same time.
