I grew up on TotalMedia Theatre 5 attentive, after I for huge sums Po *** - bought DVD and have not got it to work in conjunction with my antivirus program. TotalMedia Theatre bought via download and install. There were no problems and there is nothing that can not be played (DVD, BD).
The only problem was once a kind of interference on my laptop - there I was looking for a while until I realized that the noise disappear when I turn off hardware acceleration in the options.
Very Easy to use, no crashes, no unnecessary ballast as the competitor.
Absolute recommendation from me, but I recommend the download link, as there are fewer difficulties with upgrades generally. This download would be to lengths more expensive than the cheapest deal on Amazon box - I do not quite understand.
