Nectar απο αυτο το link που εβαλες δεν καταλαβα που φιανεται οτι η WinTV-HVR-4000 δεν ειναι συμβατη με το dscaler. Προς το παρον προσανατολιζομαι στην WinTV-HVR-3000 που κανει και τα μισα λεφτα για τα πειραματα μου και αν δω οτι δεν εχει προβλημα θα προχωρησω και στην 4000.
Παραθετω αποσπασμα απο το FAQ του επισημου site του dcaler που λεει οτι ολες οι Hauppauge WinTV ειναι συμβατες.
"Which capture card can I use ?
Almost any card (and that means A LOT) based of former Brooktree (now Conexant) chips including bt848/878/879 will work for video only. Why those ? These chips are easy to program (there has been A LOT of software based on those) and are very cheap. This means many manufacturers have (and are still) produced cards based on those chips.
Sound from the tuner is not always supported and adding this for a lot of cards is not a developement priority.
While we can't (and won't) claim "this card is the one you need", here are a few that have been sucessfully used by some users.

Take a look at the card list. This will never be complete so feel free to drop us an email reporting your experience with DScaler and your card. Also note that just because a card is on the list does not mean that it will work properly. Some features especially sound may not work correctly."
