Some of my Hi8 tapes play in fastforward motion along with the audio, but the other tapes play just fine. What can I do?

The Sony DCR-TRV130 is a D8 digital camcorder which is not compatible with Hi8 camcorders.
You need to have an Hi8 camcorder or DCR-TRV103 or similar camcorders that backward compatible with Hi8 camcorders.

hi,
what is your camcoder ? HI8 or Digital 8 did you record all the tapes with same camcoder ?
what ever HI8 doesnt go on Digital 8 and vice versa

Bad secondary sound head, needs to be replaced.

It's a Digital Hi8. Your tapes are Analog.
But it should play Analog also.
In the menu play with "PB Mode" settings.

Clean the tape heads and see if that makes a difference.  If that doesn't work, it could be the tape motor is going out.  Thats typical behavior when that happens.

I too was having a problem playing back my 8mm in my TRV460. The audio and video was both very glitchy. I tried what dyz66 said and rewound to the start of the tape,and then recorded about 10 seconds of meaninless video. After that the whole tape played nice and clear. Thanks for the idea. I believe from here on out I'm going to buy some new tapes to try and avoid this.

any brand of hi8 or digital8 camcorder will play back those tapes but sony made a tape deck made to record and play back digital8, hi8, and 8mm tape. you can get here http://www.sonystyle.com/webapp/wcs/stores/servlet/SearchCatalog

What's happening is that the tape in the cassette is being chewed on one side by the camera's tape transporting mechanism during playback, hence the distorted image and sound. The mechanism might be damaged (misalignment) or just dirty. Try not to play other tapes on this unit because they will become permanently damaged. The best way is to find another camcorder (if cleaning does not help). Note that some old cassettes of long recording time will exhibit this behavior more often because of thinner tape used.

maybe I would buy your camera,
yes as far as I know hi8 and 8mm are completely different cameras,
where are you and how much for the camera?

There are no such adapters that would allow 8mm, Hi8 and Mini DV tapes to be played in a VHS VCR. Only the old VHS-C tapes can fit and play in an adapter. There are several reasons why 8mm (or Hi8 and miniDV tapes) cannot be physically played in a VHS VCR: 1. 8mm (Hi8, miniDV) is a different format with different technical characteristics than VHS. These formats were never developed with the intention to be mechanically compatible with current VHS technology. 2. 8mm/Hi8 tapes are 8mm wide (miniDV is 6mm wide), while VHS tape is 1/2" wide, making it impossible for a VHS video head to read the taped information correctly. 3. 8mm/Hi8/miniDV tapes are recorded and played at different speeds than VHS, so even if the tapes could physically fit into a standard VHS VCR, the VCR still couldn't play back the tapes at their correct speeds. 4. 8mm/Hi8/minDV audio is recorded differently than VHS. 8mm/Hi8 audio is recorded in AFM HiFi mode, while miniDV audio is recording in 12-Bit or 16-Bit PCM digital audio format. So, even if the video could be played back in a VHS VCR, the audio could not be read properly. 5. 8mm/Hi8 video is of higher resolution than VHS and is recorded in a different bandwidth length (miniDV video is recorded digitally), so once again, a standard VCR still could not read the information correctly, even if the tape could fit into a VCR.
