I stumbled on a web page that indicated that ReplayTVs do not record the SAP (Secondary Audio Programming, I think) signal, but that Tivo has an option (perhaps global for _all_ recordings) to do record SAP (presumably in substitution for the regular audio). Certainly I couldn't find any way to get SAP on my Replay.
Previously, I didn't care about SAP at all, it is most often used for spanish dubbing, as far as I can tell, which doesn't help me. However, my mother-in-law speaks Mandarin and has recently been using my Replay to record Chinese soap operas. One she has recently wanted to watch is transmitted in Cantonese with Mandarin available via SAP.
1) Is the lack of SAP support not an issue for most ReplayTV users?
2) If Replay offered SAP support, would this mean that it would only be available if you were using Replay's tuner (or the coax input)?
The ReplayTV faq ( http://replayfaq.leavensfamily.com/
) did not seem to address this issue, which leads me to think that not many people care.
