I am having considerable trouble with 5.1 AC-3 rendering under Vegas 7.0a, and I would like to find out if others are having similar problems before I report anything to Sony/MMS.
Project Properties: HDV 720p, 5.1 Surround, 48 KHz, 24 bits.
Render Template: 5.1 Surround DVD (all defaults intact).
Problem #1: The rendered AC-3 file appears to have only the "surround" channels, no front channels or center channel (haven't checked LFE). The sound that is present (on the "surround" channels) is very weak. These results have been confirmed in DVDA 3.0c, DVDA 4.0, and on a burned DVD. The same test files render correctly with V 6.0d.
Problem #2: The AC-3 render times are several times longer than rendering from the same VEG with V 6.0d, in fact the render times under V 7 run about 12 to 15 times real time, i.e., 1 second of audio will take between 12 and 15 seconds to render. These factors are consistent up 3:50; I haven't tried a longer project.
Problem #3: AC-3 5.1 Surround will render only once without closing V 7 and reinvoking it. Second and subsequent renders within a V 7 session are corrupted.
Lots of different setting for project and render templates have been tried. They all behave as the example above. All tests work fine with V 6.0d.
V 7.0a works fine with AC-3 Stereo files. They all work as expected and render times are the same with V 6.0d.
HELP!
