I've had enough of this problem I'm encountering

Hi guys. My name's Alex and I'm new here. I decided to make an account to ask you if you know a solution to an issue I've been encountering for over a year now.

I use Vegas HD Platinum 11 to make gaming related youtube videos. Sometimes when I import a raw video file I've recorded using my Hauppauge HD PVR 2 gaming edition the file will play just fine until aaround the 50 minute mark and then freeze, the audio will continue. I can watch the raw file in its entirety using VLC so I know the file isn't corrupt. I've tried pinning down the cause of this issue and as far as I can tell it only occurs on video files that are longer than 30 minutes (although I've had some files up to an hour without this issue).

The only two ways around this annoyance are to either record in 20 minute clips or take the misbehaving file and run it through Handbrake, but this results in a loss of video quality.

Even when I record in short bursts I've found that if I record several video clips before deciding to turn them into a video one or more of the files, as short as they are, fall victim to this issue. I can tell a file is suffering the effects of the problem as soon as I import it because the little preview thumbnail near the end of the clip just shows a green rectangle instead of an image of the clip.

I have a slight suspicion that it might be a RAM issue but I don't know much at all about the inner workings of computers.

I hope I've explained this well enough, it's a nightmare to google because I can't describe it succinctly. Any help would be greatly appreciated as this really is becoming an unbearable annoyance at this stage.

I think if you do a Search, you'll find other Hauppauge users reporting similar issues. It has to to with the timecode in the file getting corrupted. Others have reported that using VideoReDo's (a purchased product from another company) Quick Stream Fix utility will fix the timecode corruption.

I own a copy of VRD and use QSF to fix timecode issues in my TiVo downloaded shows. I never edit them in Movie Studio however.

It's not just Hauppauge, it's ANY pvr/dvr, even dvd-ram recorders.
They all record transport streams. All transport streams contain errors.
Players are designed to gloss over the errors. Unpacking the raw bits for editing requires that the transport streams not have corrupt frames, GOP, or index errors.

As stated, you need to run your transport streams through VideoRedo TVSuite, TSDoctor, or something else before editing.

If the TimeCode Error is a known issue, from certain Sources.... then why can't Movie Studio have a button that says "ignore Timecode errors"
Even better, whenever the thing freezes; it just switches it in, telling you at the end " Movie Studio switched to Remove Timecode Errors for this Project XXXXXX" where the X's are the Help-File reference, so we can remember for next time.

If the Software can cope up to 30/40 minutes, then these errors must be small . . . so why is the Timecode so important?

It isn't.
It has absolutely nothing to do with timecode, nor did I use the term.

I said indexing and GOP, which can be several hundreds of frames in length. If even one b-pyramid is messed up, most of the frames between the previous and downstream ref-frame can be lost. Wikipedia will tell you more about bi-directional predictive frames and long-GOP interframe compression than I can. But remember that playback and full unpacking to raw bits are entirely different things.

Thanks for all the responses guys. I'll look into this VideoReDo software.

It was I that mentioned timecode. I was over simplifying the issue but the idea is the same. musicvid added the missing detail.
