Brian,
I have figured out how to get the U-Best files to play properly in Hoster with Windows7 however it requires a conversion process.
I utilized GSpot to determine what Codec(s) that the U-Best video files required to be played. According to GSpot both Video and Audio require the MPEG 1 Codec.
Hoster appears to be flexible with the Video Codec but utilizes the AC3 Codec for Audio. The AC3 Codec is what the Mux Button reacts to.
With that being said, the U-Best disks would require a conversion to a desired (what I used = .avi) video codec and AC3 Audio Codec.
I must say the videos play wonderfully (the video looks almost as good as being played straight off the disk) and Hoster does what is expected (the Mux Button works without flaw) after the files are converted to .avi (video codec) with AC3 (audio codec).
I am not sure why these files play in Win XP without the conversion??? I ran into the same problem with my DVD Video files when I upgraded to a Win 7 laptop.
I will send my results to Admin to see what can be done, if anything, without going through a conversion.
I can say that Microsoft has done a lot with Win 7 in a step toward "Seamlessly" eliminating Direct X (checkout the forums) and it appears that some of their product (which interacts with Hoster) is not acting the same in Win 7 as it did in Win XP (or even Win Vista for that matter).
One more thing, the conversion took less that 5 minutes (with a second party software) for the disk you sent me after it was copied to my hard drive.
MTU continues to produce a great product and Hoster 5.0 is excellent!
If you would like for me to send the procedures to convert the U-Best video files let me know. I have Microsoft "Word" and can send in that format or in a "Word Pad" file or post it here. Let me know which is preferrable.
I don't give up! It just takes me a little while to dig, learn, and then discover an answer.
Thanks!
Ken
