At this point of time we believe the problem to be a player firmware issue. We have taken and tested 10 random samples and all have tested perfectly with no problems in the warm-up.
We have had around 10 people that have reported this problem, but we have not received any disc back yet from the group seeing this glitch. Once we do we will test the disc on several players to see if we can duplicate the problem.
My guess at this point in time is that the workout blender or the premixes may cause a problem on some players. The technology used on HST is similar to that used on the Body Blast DVDs and we expect about 3% or less of players to have some issues. In most cases these issues will be small. 5 disc players seem to have the most problems from what we have seen in the past. If you have a problem please try playing the disc on your computer and see if you can duplicate the problem.
So Why do some people have a problem and others don't? Well, the short answer is your DVD player is a computer. It has a operating system and it has "drivers" or "firmware"....But perhaps this is another good time to refer you to a site called DVD Review. Their website can be found at
http://www.dvdreview.com. This is perhaps the best website on the web for information about DVDs and DVD players. I suggest you read their FAQ section which will answer many questions you may have. I know in reading the various fitness forums a lot of information that is being posted about DVDs is just not correct and the DVD Review FAQ will help to clear things up. Here is a link to the FAQ Page:
http://www.dvdreview.com/faq/dvdfaq.shtml Now getting back to why a disc will work on some players and not others, here is what DVD Review says:
Why doesn't disc X work in player Y?
The DVD specification is complex and open to interpretation. DVD-Video title authoring is also very complex. As with any new technology, there are compatibility problems. The DVD-Video standard has not changed substantially since it was finalized in 1996, but many players don't properly support it. Discs have become more complex as authoring tools improve, so recent discs often uncover engineering flaws in players. Some discs behave strangely or won't play at all in certain players. In some cases, manufacturers can fix the problem with an upgrade to the player In other cases, disc producers need to reauthor the title to correct an authoring problem or to work around a player defect. Problems can also occur because of damaged or defective discs or because of a defective player.
If you have problems playing a disc, try the following:
1. Check the list below to see if it's a reported problem. Also check the list of problem discs in DVD Review's Film Vault and at InterActual's tech support page. Try a newsgroup search at Google.
2. Try playing the disc a few more times. If you don't get the exact same problem every time, then it's probably a defective or damaged disc. Make sure the disc isn't dirty or scratched
3. Try the disc in a different player. (Visit a friend or a nearby store that sells players.) If the disc plays properly in a different player then your player is likely at fault. Contact the manufacturer of your player for a firmware upgrade. Or, if you bought the player recently, you may wish to return it for a different model.
4. Try a different copy of the disc. If the problem doesn't recur, it indicates that your first copy was probably damaged or defective. If more than one copy of the disc has problems in more than one player, it may be a misauthored disc. Contact the distributor or the studio about getting a corrected disc.
5. If it's a recordable disc (R/RW), your player might not be able to read it (see 4.3.1).
Please Note: Until we receive a disc back from a customer who has this problem we can’t say for sure if this is a player firmware issue or a disc problem. At this point in time we can only give you our best guess. We have had two customers who have received replacement disc and who have had the same problem again. This points to the problem being a player firmware issue since the chances of receiving two defective discs with the exact same problem are astronomical. .. But we will know more in a few days once we get some disc back.
