A: 

Have you considered merging the FLVs server side into a single FLV? I think you could even do this dynamically if your source FLVs all have identical CODECs and CODEC parameters.

I'd also spend more time on working out why you are having problems.

  • Have you confirmed that the FLVs were preloaded as you expected?
  • Are they being cached properly browser side?
  • Is that cache intact?
  • What exactly is the error message?

These are all details that I don't see in your question that I would be asking myself.
