Would it be so hard for MC to ask me to send them the folder with the troublesome flac files and see if they can convert to mp3, and if not, figure out why not?
I think that exact thing would and does often happen. Unfortunately, your post was somewhat poorly timed, as there are some key people at JRiver on vacation right now.
Otherwise... I'm a bit confused. In the OP I thought you said you DID rip the FLAC files with MC. Is that not the case? If MC is borking some of the tags in FLAC files, causing those files to be broken and unable to be converted to MP3, that seems like a pretty serious issue. I mean... I rip some things to FLAC, but then I ALWAYS want to convert them to MP3 (to keep it in a stack). MC needs to be able to rip to FLAC without messing up the files in a way that it can't then convert them to MP3.
If you didn't rip the original FLAC files with MC, then I think it is up to debate who bears the responsibility to fix the issue. But that doesn't seem to be what happened here.
This sort of reply from MC irks me. I see it repeatedly.
I think you are reading too much into his question. I think it was a legitimate question, not really a suggestion. There was a question mark at the end, after all.
I'm confused by why he asked it, but still... How are they expected to improve their product if they can't ask for feedback on it. His question was simply "Why not rip with MC?" Why not give him an answer, rather than a diatribe about documentation? He can't make suggestions to the team on ways to tangibly improve the ripping process without feedback. For me, for example, I'd absolutely NEVER want to rip with anything else, and I have zero desire to spend a bunch of time tagging the files pre-rip. It is so much easier to just do it later in MC.
For the record, MC's Wiki is far better documentation than MANY of the $30,000-$100,000 Digital Asset Management systems out there. I know, because I'm deeply involved in trying to find a good one for my company.
