Down conversion to 720*480?

First of all, GB-PVR is awesome.

I have a question that I couldn't find the answers by searching. This is not about aspect ratio or F7.

I'm outputing GB-PVR to 60" HDTV via Nvidia MX440 DVI connection at 1280*720 resolution in Windows.

If I play an .avi file in full screen in GBPVR, will the directshow first convert the video to 720*480 (GBPVR skin resolution) and then upconvert to 1280*720 (Windows resolution)? Or, will it convert the video to 1280*720 directly?

How about if I play recorded HDTV file in MPEG2 format? As I understand, the GBPVR records HDTV signal in its original bit stream. When it plays the file, will it first down convert to 720*480 then upconvert to 1280*720?

Internally the decoder will decode each frame to its original size, then pass it to the renderer. The renderer will then draw then frame into whatever size window it has to.

No, its exactly the same as the last example. The decoder will decode each frame to its original size (720p would be 1280x720, 1080i would be 1920x1080 etc), then pass it to the renderer. The renderer will then draw then frame into whatever size window it has to.
