[QUOTE="Anonymous, post: 51"] heya, none of my cards have hardware support on board, but if you have an ATI or specific Geforce 4 cards which have DXVA support for hardware accelerated MPEG2 decoding, you'll notice a lot less processor usage. The only DVB-T card with on-board hardware decoding (that I am aware of) is the Hauppage PVR-350. A processor speed of faster than 1.2GHz is fine for SD (Standard Digital = 720x576p (progressive) widescreen PAL), but you're needing around a 2GHz or faster for HD (High Definition = up to 1920 x 1080i (interlace)) viewing. The Avermedia has NO third party Windows support, but is supported under Linux. The VisionPlus has a few third party windows applications but is poorly supoprted by it's manufacturer. Two new cards = the DVIco and KWorld cards look good, and I know there is a revision 2 of the Avermedia card due very soon which has a much better on-board digital tuner.. so worth watching out for. XBMC on the XBOX aleady supports viewing MPEG TS (transport stream) so you can watch a SD DVB-T recording on the XBOX without having to convert the file format or anything. The XBOX doesn't have enough CPU power to decode a HD stream without being very jerky. If MediaPortal eventually supports DVB-T/ATSC cards and has a realtime video streaming function like VideoLAN then I'll be a *VERY* happy camper! cheers, Gizmomelb [/QUOTE]
