Yeah the first thing you’ve gotta fix is the terminology. You’re not burning in SD or HD, you’re burning to DVD and Bl-ray. I can stick SD footage on a blu-ray and it’ll play in SD, but it’s still a blu-ray disc and won’t play in a DVD player.
So no, there is no such thing as a DVD burned in high definition, you will need a blu-ray burner, bd-r’s and a blu-ray player. Anyone you give the disc to is going to need a blu-ray player. If what you need are DVD’s then you’re stuck with standard definition and need to find a way to make the DVD look as good as possible. Make sure that if the project is less than an hour you’re using a decent bitrate like around 8mbps.
As a side note, if you are considering a blu-ray burner for your pc, be aware that you can buy units that will burn blu-rays and dvd’s, or ones that will only burn blu-rays that are normally less expensive.

Blu-ray is a format that can play 3 different types of HD encoded video, but if you were to actually get one you’d want to render out a Sony AVC video. As for the template you’d want to use, I know you can do 1080p@24fps, but does blu-ray support 1080p@30fps, because the wikipedia entry doesn’t mention it, but I know there’s an internet 1080p@30 template that I just used last night for a snowboard video.
Anyway, you still didn’t mention what your workflow is like for DVD authoring. Are you rendering out using the DVD Architect widescreen setting? What kind of bitrate? I go 1080p to DVD all the time and yeah it looks awful compared to the source material, but it certainly looks comparable to all the DVD’s we used to make when we actually recorded video at 480i. Not VHS tapes in EP mode.

Those Sanyo Xacti files drove me up the wall back in Vegas 8 and 9, but since 10 came out it’s handled them with no problem for me. Vegas has had a lot of problems for me over the years, but it’s still my favorite NLE. I view it sort of like that Winston Churchill quote about democracy. “It has been said that democracy is the worst form of government except all the others that have been tried.”

[Christopher Key] “Yesterday I finished up an edit that clocked in at 2 hours 11 minutes – I used the bitrate calculator and when I imported the finished render into DVD architect it said it was 5.8 Gigs – but, because of these posts, I decided to go ahead and burn a disk anyway. After it was finished it said “disk space used 4.7GB” and it looks OK and plays back fine.”
That really burns me up. If windows explorer can tell you how large a file is, and Vegas can tell you the correct size AFTER you burn the disc, why can it not tell you the exact correct size before you burn it? Come on Sony, pick up your game.

One thing to note is that bitrate calculators are pretty accurate and can usually be trusted. What can’t be trusted is DVDA’s estimated size of the files on DVD. So if you have 4GB worth of data to burn to a DVD, but once it’s all in DVDA it tells you it’s gonna take up 4.8GB and won’t fit on a single-layer disc, try burning it anyway. A lot of the time it’ll burn just fine, then after burning it’ll change it’s estimate back to 4GB. It’s frustrating but what can you do?
The other thing you asked was is there a recommended length limit for creating dvd’s. I don’t know if there’s one consensus on the forums about when they start looking crummy. I personally don’t like to fit more than an hour and a half on a single layer disc if I can avoid it, but sometimes you can’t avoid it. When we have projects that go over two hours we try to divide them up onto two discs if it’s okay with the client.

I use MXF files with Sony Vegas and when my coworkers switched from FCP to Premiere Pro CS5 I suggested the same thing, but we found Premiere was taking forever to load and generating tons of conform audio files for 4 tracks of audio when we were only recording 2 channels. I don’t know why or if that’s even related but when they switched to just importing the entire bpav folders within premiere, things got a lot better.

I’m curious, after doing that, what happens if you try to edit a title or hit M and try to label a marker and use the space key? I just tried doing that and just using the F12 key and it started playing the timeline and didn’t add a space. Isn’t that behavior more annoying?

Definitely download the trial and see for yourself on your machine. I can tell you that I haven’t had any problems in Vegas 10 with 60D 1080p footage, but that’s anecdotal evidence based on relatively minor edits on small jobs using my specific machine which only has 4gb ram and an AMD Phenom II X6 1050T cpu.

I thought the main problem with Vegas’ Preview window was that it was never threaded for multiple cpus/cores? I was really hoping they were going to implement that or GPU acceleration for version 10 but I never heard anything about that happening. Just the CUDA acceleration for h264 exports.

50mbps sure seems like a lot for a 1080i file. Sony EX-1 cameras do 1080@30p at 35mbps. I’m guess that’s not the source of your problem but it did seem odd.
