What is the best choice for downloadable products like mp4 files?

[Frank71]

Hi.
I have joomla 2.5 and virtuemart 2.0. I read here, I need to buy on extension to start my downloadable file business. I want to sale large mp4 files.
My question is: which extension is the right choice to have my store running without problems?
Example : Open Tools is manage mp4 files? (because I don't see informations in the specification)
Usually I don't see informations in the specifications, just like "video" and like "media files like .jpg , pdf, .....".
So I'm ready to spend money if extension is work right for me.

I've never tried it but it really has good documentation and good reviews.

I was searching an extension myself for a single product in my online printer shop for downloading an extension http://design-it.es/diseno-web-extensiones/your-size-custom-size-virtuemart-detail but I finally decided to touch the code.

If it is just a single product or category it's quite simple, if not I recommend acquiring the extension. What I did was sending withing the payment confirmation email, a download link, only valid for 15 days or 5 downloads.

Regards.
