Burning a CD-A "should" re-sample (convert) to 44.1.
Maybe I'm missing something here but, have you tried changing the sample rate in Sound Forge via Fie> Properties> Format & change the playback sample rate to 44.1k (or what ever the intial record rate was, to get the correct speed/pitch) and then re-sample to 44.1.
Changing the sample rate settings in Vegas seams to do nothing.
I have resampled in Sound Forge, but even when doing the full resample (and not just changing the tag) the file will still be very slow when I burn the cd.
With the files that were mistakenly recorded at 48K, they only play correctly when my master clock is set to 48K no matter if I resample them to 44.1K, 48K, 96K, etc.
The correct way to use a 48K file in Vegas to create a 44.1K CD is to drop the file on the timeline and burn the CD. No other steps are necessary. If you have a file that is misbehaving then the file is the problem, not Vegas.
Changing the 'sample rate settings' should confuse everything nicely.
In Vegas (or CD-Architect) you can have whatever file format, sample-rate, and bit-depth you like on the timeline.
You burn it straight from the timeline to CD - the conversion is done automatically and invisibly.
Or in Vegas you can render it to a WAV file with the specs as 44K1 and 16-bit, then export it to another CD-burning app..
If you must resample it in SF, then that will no change the pitch or tempo. I suspect you are over-complicating things and in the process actually fiddling with some setting to give you your wonky results.
