I used to use Audio DVD Creator all the time but as computers became faster and hard drives became larger I simply saved everything to the hard drive. Just playback via the computer's sound card.
A couple of years ago I revisited Audio DVD Creator, my intent was to burn discs to play in my truck. I burned a couple discs but then changed out the deck in the truck to one which wouldn't play the discs. It would play AC-3 but not PCM.
Along the way I discovered a similar program Music DVD Creator but was unable to purchase a licence for it despite the links on the site still working. It took the company that collects the licence fee for the software company awhile (over a month) to determine that Blaze Video was now defunct.
As for not being gapless, I don't recall that but I can well imagine. The gapless problem has come up many times with many different applications. The solution is usually to create one large file with a cue sheet. I don't think Audio DVD Creator supports that.
I tried to fire up Audio DVD Creator on my computer and for some reason it is no longer working.
Roxio has the ability to create Audio-DVD discs. I'm using Roxio Creator 2010 Pro. I dismissed using it previously as if you select "Create DVD Music Discs" it is rather basic and converts audio to AC-3. If you select "Create Music Disc Projects" instead you have access to more features and under settings can select PCM. I successfully burned a disc last night but haven't play tested it yet. Is it gapless, likely not and I see no way to load a cue sheet.
Ok wait...I was able to track down a version of Roxio Creator Pro 2011, and doing this SEEMS to give me gapless audio, but its kinda hard to tell as VLC isnt amazing at playing dvd isos on my end Im 99% sure this is doing exactly what I want it to do, just need to get a DVD-R and burn a test disc to make sure, it plays gaplessly on VLC sometimes but sometimes it doesnt, i think that may be a quirk with VLC rather than the program. Thank you so much for mentioning Roxio!!!!! Never heard of the program before and this is quite useful in general.
EDIT: IT ***IS*** playing gapless! Thank you!!! Here's a full tutorial for anyone else who may want to do this:
Music/Audio-->Create-->Create Music Disc Projects
Once you click this, under Project Type, click DVD Music Disc. After that, click Project Settings, once you click that, youre gonna see a dropdown menu that says "Audio Format", click that and click "Uncompressed audio (PCM)"
After you do that, you may need to re-add any tags for what you're burning, as for some reason it wont read tags on my end, it does have an automatic tag adder that i havent seen any issues with yet.
Only real issue here is that for whatever reason it refuses to accept 24bit files, which for me thats fine, as 16bit through my blu-ray player still sounds better than 24bit through the line out on my DAP, but that may bother others.
