advantages of m2t format...

My question is about the advantages of m2t format.
I have a HVD video cam (sony hcr-hc3) and it is adequate for home use...
Direct to a DV avi file via WinXp tools seems to work fine and gives me relatively good 1080i videos takeing 20 minutes to capture a 20 minute video (size approx 4GB/20minutes)

If I capture to a m2t file and then want to redor it out to an dv avi file it takes about approx 5-7min per minute of video to rendor... I am not running any filters and have not inserted any transitions or edited the track... I am just tring to get a unmodifiied avi video of the original video that I can archive/distribute before I start playing...

Is there any way to speed this up for direct rendors to DV avi for this unedited m2t file ? Or do I just have to wait ???
Are there any inexpensive h/w acceleration options ?

Are there any advantages of gong to the m2t format ?

I suppose I should have captured to avi first and archived that.
Then captured to m2t format ?

Tips for speed here

XP's capturing tools don't support HDV btw, so what you get is plain DV, not HDV 1080i. This means that after editing, you have a loss of quality. The right thing to do is to use Vegas' own HDV capturing tool (although I highly suggest you upgrade to v9.0 to get proper support for HDV), and then edit as HDV. At the end, export as you wish.

HDV is heavier than DV, so it will take more time to export. AVCHD is way heavier than HDV too.

Thanks for the tips... The xp capture tool seems to work ok but I think you are right that there is a quality loss...

I am in the process of upgrading to a quad-core host and v9 for rendering hopefully this will help the speed issue a little...

Thanks again!
