Unfortunately recording of meetings using the client relies on the streams being captured locally to the client and cached on disk, then rendered after the meeting.
If your recording client suffers poor quality throughout the meeting, this will be reflected in the recording file.
I had an issue with my W10 client a while ago where it would fail to render the video for no reason. It eventually fixed itself after an update to the OS. So maybe updating your OS and Skype client may help a little towards your problems.
IMO the recording feature could be better, especially with video quality. If Microsoft bring out cloud recording for conferences then this will mitigate and solve a lot of these problems. Hopefully soon! Please :)
