A:AnswerThe device should work with any HDMI input from any RCA output. My application was from a Sony VHS VCR RCA output to a fifty inch Samsung flat screen HDMI input.
A:AnswerThe fifteen dollar device may in fact work fine. I was very satisfied with the sixty dollar product. There were no schematics included to determine how the A/C power is applied to the quality or function.
A:AnswerYour Bose system should be connected optically with your TV. The DVD player can be connected through this converter. Then all should work fine.
A:AnswerI don't believe so. Converters are uni-directional. This particular unit converts FROM the RCA plugs TO the HDMI. What you need is the reverse. You're trying to go FROM an HDMI TO an RCA. (That's why the other person could plug their old VCR into the new TV and play their movies, but could not record. The digital info only flows one direction through these.)
