Hello,
I just tested the new version x64, it works great, however the recording does not work, I click on record, I validate (video / audio / subtitle), and he says to me: "Error open D:\TV Enregistrées\RTS Un - 2017-10-29.ts to recording!!". Under the x86 version no worries under the same folder.
Test as an administrator and in normal mode.
Otherwise for MPEG2 channels I find the opening of the stream faster than the 32 bit version. For example, I have a channel called MOSAIK TV, and in the 32-bit version, you have to click several times on the channel for the video to start, while in version 64, it opens directly.
Congratulations for this version, and good luck.
BR.
