Being a completely computer-run channel MoonTV was prone to various technical malfunctions. During its run the channel "went dark" several times. The periods of darkness could last anywhere from a few minutes to a whole week. Additionally, the fact that the channel was not supported by a bigger, better established channel (such as SubTV which is a part of MTV3) undoubtedly had effects in the overall production values of the channel's programmes. Unlike other commercial channels, MoonTV did not feature subtitling for programmes, regardless of their language.
