I read a review of the RC that says it has new drivers which support DVXA hardware acceleration for ATI and Nvidia cards in MCE. Has anyone tried this yet with any success? The review said this feature was not in release 7100, which I have and had understood was effectively the RC.

My setup runs TV3 at 15% CPU when I use 7RC so I just assumed it was using HW accel. Nvidia Card.

Any chance someone could post links to a couple of DVB-T H264 WTV sample files for me? 30 seconds should be plenty. I am building a Windows 7 RC media center system from scratch, and I would really like to know if my machine can play the files before I clamber on to the roof and muck around with the UHF aerial! :-)

smbunn, 7100 is the RC and Mpeg & h.264 HW acceleration were also present in Win7 Beta. The reviewer is mis-informed.

Probably something to do with the secure video path needing WHQL certified drivers to work properly for Blue Ray... or along those lines.

Slightly off topic but has anyone figured how to get WTV files translated to MPEG? The RC of windows 7 has a conversion function to the old media centre format but this doesn't work with H.264 content.

Thanks

Unfortunately for us ATI users, the W7 H.264 codec is even worse for interlaced content than the PowerDVD8 ones (which are just usable)

This is a really stupid question team - but why no sound replaying .ts files from freeview under RC1?

GoodSync

GoodSync. Easily back up and sync your files with GoodSync. Simple and secure file backup and synchronisation software will ensure that your files are never lost (affiliate link).

The Win7 codecs for NZ Freeview are only operating in live tv (out of the box). The video and movie parts are using MPEG so no sound (at least that's what I think). We're having a discussion on it over in HTPC.
