How often do you get a "content not available" message from your cable provider?

I have Time Warner cable here in Austin. The basic package comes with several varieties of on demand content and features. Some examples of this are an on demand “test drive” of various automobiles for those comparison shopping. Another example is the “start over” feature for some shows in case you miss the first part.

For the most part, I rarely watch TV, much less try to access the on demand content. However, there have been a few times that I have tried to use the “start over feature”. It has never worked ever. I have not been able to view a single frame of (non-pay per view) on demand content. I always get a “content not available message” any time I try to use the start over feature.

So… anyone else have this difficulty. Is this just another example of a big company promising features that they are unable or unwilling to actually deliver?
