I've never heard of infrared being used for megahertz range transmission... as serial data goes, it's in the kilohertz range: http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=1967024&k=ir%20receiverTSOP 38.0 KHZ based on those search results.

oh thanks a lot, yeah you are righ 38 khz not 38 mhz. i'm forgot.
Glad it helps - whatever you make, try and get photos and throw up an instructable or slideshow!
i have one, https://www.instructables.com/id/portable-amplifier-10W-for-iPod-cellphone-etc/
If I were you I'd use a VS1838B (but it doesn't work very well in sunlight) or a TSOP38238 (or are those gone like the other TSOP you couldn't find?)
BTW there's a list of TSOPs here, but most of them are for more than 38khz, which might make them more expensive?
