This isn't really the correct forum for posting your question since we deal with hacking Tivos and not ReplayTVs. The ReplayTV forum at the AVS Forums is probably to most active forum for ReplayTV hacking. I wouldn't expect to find an answer to your question over there either since it's pretty much a forbidden topic. Hacking any PVR for the express purpose of theft of service is not allowed in any forum that I know of. I'd be willing to bet that some company will eventually pick up the Replay service. If not, I would imagine that SonicBlue will at least have to support it for a certain amount of time, but that may simply be wishful thinking on my part. Just because a company files for bankruptcy doesn't always mean that they will go out of business. I don't know all of the details of SonicBlue's situation so I can't say for sure either way. I doubt if anybody really knows what will happen at this point. If you're really concerned then why not unload your Replay on ebay and get yourself a Tivo? Tivo doesn't show any signs of going out of business any time soon. If you get a DirecTivo then you should be safe since DTV handles all of the DTivo services (i.e. both DTV and DVR subs).
Please don't PM me or any other members looking for personal assistance.
