VLC-capture streaming ".ts" file to QuickTime - what are best VLC settings?

Question

I captured a Webcast of a U.S. House Appropriations Committee hearing to disk with VLC (making a ".ts file") but am having trouble working with it. Although VLC will play it fine, QuickTime and MPEG Streamclip (where I hoped to convert it) will not. MPEG Streamclip plays it, but without audio. I've tried various kinds of Streamclip conversions to no avail (and I have Perian and QuickTimeMPEG2.component, which often solve problems). Two questions: Generally speaking, if you can't hear the audio playing it in MPEG Streamclip, is it likely that doing conversions with Streamclip aren't going to help you? And #2, for future reference, what would be the optimal settings in VLC to make a ts file that will be QuickTime-friendly (or at least MPEG Streamclip friendly where I can export or convert to something that QuickTime will accept).
P.S. -- Codecs shown in VLC under Properties are:
Stream 0: MPEG Audio Layer 1/2/3 (mpga)
Stream 1: MPEG-1/2 Video (mpgv)

Generally speaking, if you can't hear the audio playing it in MPEG Streamclip, is it likely that doing conversions with Streamclip aren't going to help you?
I would normally think not. However, as this is not a normal work flow for me, would you happen to have a short sample clip to play with for testing purposes?
#2, for future reference, what would be the optimal settings in VLC to make a ts file that will be QuickTime-friendly (or at least MPEG Streamclip friendly where I can export or convert to something that QuickTime will accept).
No TS, MTS, or M2TS content is compatible with QT since it only handles program stream files. As to MPEG Streamclip, again this is uncharted territory for me and I would need to run my own tests on a sample file before saying anything definitive.
